Available in PDF, EPUB and Kindle. Book excerpt: In a renewable energy system, multiple energy sources (such as combining renewable energy and energy storage) are utilized together to enhance the overall energy conversion reliability since renewable energy, such as wind and solar, are intermittent in nature. In conventional power architecture, each energy source requires a dedicated individual power converter to perform specific control or power management function. To reduce the overall number of circuit components, multi-input converter (MIC) configuration provides a cost effective power architecture when multiple energy sources are utilized, as they can use fewer filter circuit components and utilize smaller system space. To maximize the features offered by MICs, a truly power efficient and compact MIC should utilize minimal number of active switching components with soft-switching features, while at the same time, assist each energy power interface to achieve all the required control functions. In the first part of this thesis, a class of several soft-switched DC-DC MICs is proposed, where each input module of the devised MICs utilizes only a single switch. Each of the presented MIC circuits can also be integrated with a front-end (either single phase or three phase) AC-DC stage without adding additional switches to interface with renewable energy generation unit that outputs an AC voltage. In addition, input power factor correction is also provided. The second part of this thesis investigates the use of the devised DC-DC MIC circuit to improve the double power conversion steps typically seen in a solar-battery energy conversion system with a common DC grid that utilizes a bi-directional energy storage power converter. This chapter focuses on the development of a soft-switched MIC circuit that consists of integrated unidirectional energy storage (i.e. battery) power interface, for use in module-connected solar energy power optimizer system with distributed energy storage. In the proposed circuit, the storage charging (storage absorbs power) circuit is integrated with the input stage of the main converter via high frequency AC link, whereas the storage discharging (storage delivers power) circuit is connected to the output stage of MIC. As a result, energy is directed from the input to the battery and from the battery to the load through a single power conversion step. The third part of this thesis utilizes the circuit concepts devised previously to develop a new soft-switched MIC configuration that consists of an integrated unidirectional energy storage power interface, as well as to provide output voltage regulation. Hence, the proposed MIC is applicable for both regulated and unregulated grids. The control mechanism of the proposed system is presented. The operating principles and characteristics of each proposed converter topology are provided in detail. Simulation and experimental results on proof-of-concept prototypes are provided to demonstrate the functionalities of each devised MIC topology.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, a new satellite platform power architecture based on paralleled three-port DC/DC converters is proposed to reduce the total satellite power system mass. Moreover, a four-port DC/DC converter is proposed for renewable energy applications where several renewable sources are employed. Compared to the traditional two-port converter, three-port or four-port converters are classified as multi-port converters. Multi-port converters have less component count and less conversion stage than the traditional power processing solution which adopts several independent two-port converters. Due to their advantages multi-port converters recently have attracted much attention in academia, resulting in many topologies for various applications. But all proposed topologies have at least one of the following disadvantages: 1) no bidirectional port; 2) lack of proper isolation; 3) too many active and passive components; 4) no soft-switching. In addition, most existing research focuses on the topology investigation, but lacks study on the multi-port converter's control aspects, which are actually very challenging since it is a multi-input multi-output control system and has so many cross-coupled control loops. A three-port converter is proposed and used for space applications. The topology features bidirectional capability, low component count and soft-switching for all active switches, and has one output port to meet certain isolating requirements. For the system level control strategy, the multi-functional central controller has to achieve maximal power harvesting for the solar panel, the battery charge control for the battery, and output voltage regulation for the dc bus. In order to design these various controllers, a good dynamic model of the control object should be obtained first. Therefore, a modeling procedure based on a traditional state-space averaging method is proposed to characterize the dynamic behavior of such a multi-port converter. The proposed modeling method is clear and easy to follow, and can be extended for other multi-port converters. In order to boost the power level of the multi-port converter system and allow redundancy, the three-port converters are paralleled together. The current sharing control for the multi-port converters has rarely been reported. A so called "dual loop" current sharing control structure is identified to be suitable for the paralleled multi-port converters, since its current loop and the voltage loop can be considered and designed independently, which simplifies the multi-port converter's loop analysis. The design criteria for that dual loop structure are also studied to achieve good current sharing dynamics while guaranteeing the system stability. The renewable energy applications are continuously demanding the low cost solution, so that the renewable energy might have a more competitive dollar per kilowatt figure than the traditional fossil fuel power generation. For this reason, the multi-port converter is a good candidate for such applications due to the low component count and low cost. Especially when several renewable sources are combined to increase the power delivering certainty, the multi-port solution is more beneficial since it can replace more separate converters. A four-port converter is proposed to interface two different renewable sources, such as the wind turbine and the solar panel, one bidirectional battery device, and the galvanically isolated load. The four-port converter is based on the traditional half-bridge topology making it easy for the practicing power electronics engineer to follow the circuit design. Moreover, this topology can be extended into n input ports which allow more input renewable sources. Finally, the work is summarized and concluded, and references are listed.

This book was released on 2006 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Electrolyser is a part of a renewable energy system (RES) and generates hydrogen from water electrolysis that is used in fuel cells. A dc-to-dc converter is required to couple the Electrolyser to the system DC bus. This thesis presents an extensive comparison of three soft-switched high-frequency transformer isolated dc-to-dc converters for this application. It is shown that LCL-type series resonant converter (SRC) with capacitive output filter is suitable for this application. Due to the wide variation in input voltage and load current, no converter can maintain zero-voltage switching (ZVS) for the complete operating range. To overcome this problem, two new converter configurations are proposed. Proposed Configuration 1 is a two-stage boost-LCL SRC with capacitive output filter and Proposed Configuration 2 is a transient-boost dual half-bridge LCL SRC with capacitive output filter. Operating principle, design, simulation and experimental results of the newly proposed converters are also presented.

Book excerpt: The development of renewable energy systems (e.g. wind and solar) is significant to cope with an energy crisis yet, at the same time, it presents challenges to the grid for their MW-scale integration due to their volatile characteristics. Battery energy storage systems are essential in providing sustainable power and improving the overall system reliability effectively with the large deployments of renewable energy conversion systems. Bidirectional power converters are responsible for transferring power between the battery energy storage system and the grid. Selecting an efficient and cost-effective power topology along with a reliable control system is critical to ensure that the energy storage system operates safely with prolonged service life and minimized maintenance cost. In this dissertation, a multi-mode stacked-switch leg with soft-switching capability for use in bidirectional DC/DC converters is proposed for battery energy storage applications. This dissertation consists of three parts. The first part focuses on the development of a bidirectional soft-switched converter utilizing a CLLC resonant circuit and the proposed multi-mode switching legs. The presented leg is able to facilitate multiple operating modes to enable high voltage gain under different operating conditions and allow the converter to operate with a much lower output voltage ripple (50%) compared with the conventional stacked-switches-based converter topology. In the second part of this thesis, a fault-tolerant control scheme is proposed which enables seamless post fault operation of the presented multi-mode DC/DC converter if any switches in the presented leg experience an open-circuit fault. In the third part of this thesis, a comprehensive hybrid control system is proposed so that the overall voltage gain range of the converter is widely extended with a narrow switching frequency range (less than 10% of the base frequency), while at the same time, the efficiency of the converter is improved over the whole gain range (more than 1%). The operating principles and characteristics of the proposed converter and the proposed control schemes are explained in detail in this thesis. The performance of each of the presented circuit and control concepts is verified through simulation as well as experimental results on silicon-carbide (SiC)-based proof-of-concept hardware prototypes.
