Multiphase Bidirectional Flyback Converter Topology for Induction Motor Drive

For hybrid electric vehicles, the batteries and the drive dc link may be at different voltages. The batteries are at low voltage to obtain higher volumetric efficiencies, and the dc link is at higher voltage to have higher efficiency on the motor side. Therefore, a power interface between the batteries and the drive’s dc link is essential. This power interface should handle power flow from batt...

Novel High-Conversion-Ratio High-Efficiency Isolated Bidirectional DC-DC Converter

In addition to improvements in the conversion efficiency of green energy, the storage and reuse of excess energy have become important research topics. Thus, high-step-up/step-down converters have become important research subjects. Converters with high conversion ratios can be used in energy storage systems, high-intensity discharge lamps, high power applications, communication power, solar po...

A High-Efficiency Isolated-Type Three-Port Bidirectional DC/DC Converter for Photovoltaic Systems

This paper proposes a novel high-efficiency isolated three-port bidirectional DC/DC device for photovoltaic (PV) systems. The device contains a high step-up converter for PV modules to supply power to the DC bus, and a bidirectional charge/discharge control circuit for the battery with an improved boost-flyback converter. When the PV modules supply sufficient energy, their output can be stepped...

High-Efficiency Isolated Bidirectional Ac–Dc Converter for a Dc Distribution System

The isolated bidirectional ac–dc converter is for the 380-V dc power distribution system to control the bidirectional power flow and to improve its power conversion efficiency. Here the high-side switches of the ac– dc rectifier employ IGBTs without anti-parallel diodes and SiC diodes. In addition, the low-side switches are consisting of two MOSFETs to reduce the conduction loss in the rectific...
