SiC-Based High-Frequency Soft-Switching Three-Phase Rectifiers/Inverters
Three-phase rectifiers/inverters are widely used in grid-tied applications. Take the electric vehicle (EV) charging systems as an example. Within a certain space designated for the chargers, quick charging yet high efficiency are demanded. According to the current industry practice, with a power …

Design of Extreme Efficiency Active Rectifier for More-electric Aircrafts
… carrying out the task is commonly known as "rectifiers". This work aims at designing and constructing rectifiers that can work efficiently and reliably in more-electric aircrafts. One of the major challenge for these rectifiers comes from the complex aircraft environment. The ambient …

A dual/high-voltage automotive electrical power system with superior transient performance
… averaged models for synchronous machines and three-phase rectifiers with constant-voltage loads are developed. A load-matching technique based on a switched-mode rectifier is introduced and used in conjunction with the developed machine/rectifier models to design the new high-power, …

Design of High-Density Filter Building Blocks for SiC-based Three-Phase Power Converters
… utility interface with grid-tied applications (three-phase rectifiers or back-to-back converters) in the form of high CM and DM emissions, total harmonic distortion (THD) and current harmonics. While at the motor end, long cable and bearing/leakage current effects are prevalent. As such, …

Novel DC/DC Converters For High-Power Distributed Power Systems
… based on the two-stage approach for high-power three-phase DPSs, the DC-link voltage coming from the power factor correction (PFC) stage penalizes the second-stage DC/DC converter. This DC/DC converter not only has to meet the characteristics demanded by the load, but also must process energy …

PCB-Based High-Power DC/DC Converters with Integrated Magnetics for Battery Charger Applications
… EVs is proposed. The first stage is a four-phase bridgeless totem pole AC/DC converter working at critical conduction mode (CRM) so that soft switching can be achieved for all the fast switches. The second stage is single phase CLLC (1PCLLC) converter which is attractive due to its less …
