Available in PDF, EPUB and Kindle. Book excerpt: Power conversion for the myriad low-voltage electronic circuits in use today, including portable electronic devices, digital electronics, sensors and communication circuits, is becoming increasingly challenging due to the desire for lower voltages, higher conversion ratios and higher bandwidth. Future computation systems also pose a major challenge in energy delivery that is difficult to meet with existing devices and design strategies. To reduce interconnect bottlenecks and enable more flexible energy utilization, it is desired to deliver power across interconnects at high voltage and low current with on- or over-die transformation to low voltage and high current, while providing localized voltage regulation in numerous zones. This thesis introduces elements for hybrid GaN-Si dc-de power converters operating at very high frequencies (VHF, 30-300 MHz) for low-voltage applications. Contributions include development of a new VHF frequency multiplier inverter suitable for step-down power conversion, and a Si CMOS switched-capacitor step-down rectifier. These are applied to develop a prototype GaN-Si hybrid dc-dc converter operating at 50 MHz. Additionally, this thesis exploits these elements to propose an ac power delivery architecture for low-voltage electronics in which power is delivered across the interconnect to the load at VHF ac, with local on-die transformation and rectification to dc. With the proposed technologies and emerging passives, it is predicted that the ac power delivery system can achieve over 90 % efficiency with greater than 1 W/mm2 power density and 5:1 voltage conversion ratio. A prototype system has been designed and fabricated using a TSMC 0.25 [mu]m CMOS process to validate the concept. It operates at 50 MHz with output power of 4 W. The prototype converter has 8:1 voltage conversion ratio with input voltage of 20 V and output voltage of 2.5 V. To the author's best knowledge, this is the first ac power delivery architecture for low-voltage electronics ever built and tested.

This book was released on 2018-06-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides a concise and thorough reference for designing electrical and electronic systems that employ adjustable speed drives Electrical and electronic systems that employ adjustable speed drives are being increasingly used in present-day automation applications. They are considered by many application engineers as one of the most interfering components, especially in a contemporarily faced industrial environment. This book fills the gap between the high-level academic knowledge in the electromagnetic compatibility (EMC) field and the recommended practical rules for assuring electromagnetic compatibility margin. It focuses on finding and formulating the issues that often occur with the generation and propagation of conducted emission in AC motor drives fed by frequency converters, rather than proposing specific solutions for dealing with them. It also features explanations of selected academic backgrounds of EMC and presents practical case studies. The book starts with an introduction to conducted emission in adjustable speed drives. It then goes on to offer in-depth chapters covering conducted emission origins in switch-mode power converters; conducted emission generation by frequency converter in adjustable speed drives (ASD); propagation of motor side originated conducted emission towards the power grid; modeling of conducted emission in ASD; broadband behavior of ASD components; and impact of a motor feeding cable on CM currents generated in ASD. In addition, this resource: Presents state-of-the-art analysis of undesirable high frequency phenomena accompanying AC motor speed control Discusses the fundamentals of phenomena of electromagnetic interference (EMI) generation in switch mode static converters Provides methodology of modeling-conducted EMI generation and propagation in ASD High Frequency Conducted Emission in AC Motor Drives Fed By Frequency Converters: Sources and Propagation Paths will appeal to scholars and a wide range of professionals who are involved in the stages of development, design, and application of adjustable speed drives in accordance with ever-increasing EMC requirements.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a novel AC power delivery architecture that is suitable for VHF frequency (50-100MHz) polyphase AC/DC power conversion in low voltage integrated circuits. A complete AC power delivery architecture was evaluated demonstrating the benefits of delivering power across the interconnect at high voltage and lower current with on- or over-die transformation to low voltage and high current. Two approaches to polyphase matching networks in the transformation stage are compared: a 3-phase system with separate single-phase matching networks and individual full bridge rectifiers, and a 3-phase delta-to-wye matching network and a 3-phase rectifier bridge. In addition, a novel switch-capacitor rectifier capable of 3V, 1W output, was evaluated as an alternative circuit to the diode rectifiers. A 50MHz prototype of each version of the system was designed and built for a 12:1 conversion ratio with 24Vpp line-to-line AC input, 2V DC output and 0.7W output power. The measured overall system efficiency is about 63 % for the 3-phase delta system. Although the application is intended for an integrated CMOS implementation, this thesis primarily focuses on discrete PCB level realizations of the proposed architectures to validate the concept and provide insights for future designs.
