Download or read book Analysis of Power Factor Correction Converters written by Thomas Yeh and published by . This book was released on 1992 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Power Converter with capacitive input filter is a non-linear load to the Utility AC power lines. There are widely used as Switch-Mode Power Supplies in office equipment applications ranging from Personal Computers to Office Printers and Copiers. The distorted input current waveform extracted by the capacitive input filter of the power converters produces unwanted harmonics which propagates to other line powered equipments. The harmonic pollutes the AC lines and interferes with the operations of sensitive line powered equipments. The distorted current waveform also leads to inefficient utilization of the available power from the AC outlet. This is because the AC line power is transferred to the load only when each frequency component of the line voltage is an in-phase, scaler related quantity with respect to the same frequency component of the extracted current. The problems of poor power factor and harmonic distortion are compounded by the proliferation of Switch-Mode power supplies and the situation is rapidly becoming intolerable. The problem of poor quality input current waveform can be described by two quantitative measurements: Power Factor (pf) and Total Harmonic Distortion (thd). Two general approaches are available to remedy the problem. One approach is to install passive filter networks between the Utility AC lines and the capacitive input filter. The second approach is to design active power processors as dedicated Power Factor Correction (pfc) Converters and installed as the front end to the capacitive input filter to shape the distorted current waveform into waveforms which will yield higher power factor. This Thesis first introduce the general concept of PF and harmonic distortion in Chapter 1. Chapter 2 derive the mathematical description of pf based on the concept of real power (pR) and apparent power (pA). Both sinusoidal and nonsinusoidal cases are studied. For comparison and completeness, two popular passive power factor correction filter networks are analyzed in Chapter 3 to derive the maximum achievable power factor for each network along with the corresponding harmonic distortions. Governing equations are derived and presented graphically as a function of the filter network and load parameters. Chapter 4 provides the analysis of active power factor correction using switch mode Boost Converter. The analysis is carried out for two types of current controllers used as the current modulators for current waveform shaping. The state space averaged modeling approach is employed to derive the mathematical model of the Boost Converter suitable for large signal time domain and small signal frequency domain analysis. The model is further extended to derive the describing equations for the Boost Converter operating as pfc converter. Characteristics of the two current controller functions impacting the pfc operation are studied to expose their relative strength and limitations. The analysis includes the supplementation of the current control loop by an outer voltage control loop to regulate the output capacitor voltage of the pfc converter. The large signal analysis is first investigated for PF, waveform quality and voltage regulation. The small signal analysis follows to extract the frequency domain behavior of the pfc Boost Converter. The limitation of the voltage control bandwidth and its effect on the achievable pf is discussed. Chapter 5 verified the analysis through computer simulation using PSPICE. The original works of Bello based on Berkeley SPICE are modified for PSPICE. The models are extended to implement the PFC control functions and simulated in both large signal time domain and small signal frequency domain. Both the analysis and computer simulation results are compared to a published design of pfc Converter."--Abstract.

This book was released on 2012-05 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single phase high power factor rectification is the most frequently accomplished using a boost converter. The input current shaping approach results in low line currents harmonic distortion and a power factor close to unity at the interface between the ac line and the rectifier. Various techniques are available for active current shaping, average current mode control, nonlinear control and one cycle control. Most of them are now supported by dedicated integrated circuits. Average-current-mode control is the regular control where the inductor current is forced to follow the input voltage. Recently nonlinear phenomena have been obvious in AC/DC converters which results in unstable regime such as period doubling and chaos. During these operating regimes, the input current distorts and therefore, breaks the operation of PFC converters. In this book, a study for stability for the three practical controls of boost PFC converter is introduced. Each technique has been tested to determine the practical limitation for stable regions. Design guidelines are made clear for stable operation in the examined control techniques. Experimental results confirm simulation with good matching.

Download or read book Soft Switching for Improving the Efficiency and Power Density of a Single-phase Converter with Power Factor Correction written by Tine Konjedic and published by . This book was released on 2015 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the possibilities for increasing the power conversion efficiency and power density of a single-phase single-stage AC-DC converter with power factor correction capability. Initially, the limitations are investigated for simultaneous increase of power density and efficiency in hard switched bidirectional converters. The switching frequency dependent turn-on losses of the transistors have been identified as the main limiting factor. In order to avoid the increase in total power losses with increasing the switching frequency, a control approach is proposed for achieving zero voltage switching transitions within the entire operating range of a bidirectional converter that utilizes power transistors in a bridge structure. This approach is based on operation in the discontinuous conduction mode with a variable switching frequency. Operation in the discontinuous conduction mode ensures the necessary reversed current that naturally discharges the parasitic output capacitance of the transistor and thus allows this transistor to be turned on at zero voltage. On the other hand, the varying switching frequency ensures that the converter operates close to the zero voltage switching boundary, which is defined as the minimum required current ripple at which zero voltage switching can be maintained. Operation with the minimum required current ripple is desirable as it generates the lowest magnetic core losses and conduction losses within the power circuit. The performance and effectiveness of the investigated approach were initially verified in a bidirectional DC-DC converter. A reliable zero voltage switching was confirmed over the entire operating range of a bidirectional DC-DC converter, as well as the absence of the reverse recovery effect and the unwanted turn-on of the synchronous transistor. In order to justify its usage and demonstrate its superior performance, the proposed zero voltage switching technique was compared with a conventional continuous conduction mode operation which is characterized by hard switching commutations. After successful verification and implementation in a bidirectional DC-DC converter, the investigated zero voltage switching approach was adapted for usage in an interleaved DC-AC converter with power factor correction capability. Comprehensive analysis of the converter's operation in discontinuous conduction mode with a variable switching frequency was performed in order to derive its power loss model. The latter facilitated the design process of the converter's power circuit. A systematic approach for selecting the converter's power components has been used while targeting for an extremely high power conversion efficiency over a wide operating range and a low volume design of the converter. The final result of the investigations performed within the scope of this thesis is the interleaved AC-DC converter with power factor correction capability. Utilization of interleaving allows for increasing the converter's power processing capability, reduces the conducted differential mode noise and shrinks the range within which the switching frequency has to vary. The proposed zero voltage switching control approach was entirely implemented within a digital signal controller and does not require any additional components within the converter's circuit. The experimental results have confirmed highly efficient operation over a wide range of operating powers. A peak efficiency of 98.4 % has been achieved at the output power of 1100 W, while the efficiency is maintained above 97 % over the entire range of output powers between 200 W and 3050 W.
