Characterization and Application of Wide-Band-Gap Devices for High Frequency Power Conversion
… packaging, a GaN-based MHz totem-pole PFC rectifier is demonstrated with 99% peak efficiency and 700 W/in3 power density. The switching frequency of the PFC is more than ten times higher than the state-of-the-art industry product while it achieves best possible efficiency and power density. …

Control Strategies for Minimizing the DC-Link Capacitance in Power Electronics Converters for Aircraft Electrical Power Systems
… First, a BSG based 270V DC system using a diode rectifier is investigated in which the DC-link voltage regulation is obtained through the excitation control of the exciter SG using a two-quadrant DC chopper. A steady-state feedforward duty ratio and output power-based feedforward exciter field …

PCB-Based Heterogeneous Integration of PFC/Inverter
… counterparts. In a power factor correction (PFC) rectifier/inverter, the totem-pole configuration with critical conduction mode (CRM) operation to realize zero-voltage switching (ZVS) is deemed most desirable for a switching frequency 10 times higher than current practice. With a significantly …

High-Frequency Quasi-Single-Stage (QSS) Isolated AC-DC and DC-AC Power Conversion
… soft-switched single-phase QSS bi-directional inverter/rectifier (charger) topology is derived based on the QSS power conversion concept. A simple active voltage clamp branch is used to clamp the otherwise high transient voltage on the current-fed ac side, and at the same time, to achieve …

Modified Space Vector Modulation for a Zero-Voltage Transition Three-Phase to DC Bi-directional Converter
… transition three-phase voltage source inverter/boost rectifier is presented. The converter is intended for high performance medium power applications requiring bi-directional power flow. The proposed modified space vector modulation allows the main switches to be operated with constant …

High Performance Power Converter Systems for Nonlinear and Unbalanced Load/Source
… four-legged voltage source converters, including inverters and rectifiers. The four-legged power converters with three-dimensional space vector modulation schemes have a better DC link voltage utilization and result in a low distortion. It is an effective solution to provide the neutral point for …
