This paper presents a bidirectional DC-DC converter suitable for low-voltage super capacitor-based electric energy storage systems. The DC-DC converter presented here consists of a full-bridge circuit and a current-fed push-pull circuit with a high frequency (HF) transformer-link. In order to reduce the device-conduction losses due to the large current of the super capacitor as well as unnecess...

A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

A configuration of a single-phase full-bridge AC-DC converter and dual active bridge (DAB) converter used in V2G (vehicle to grid) and G2V (grid to vehicle) technology is proposed in this paper. It can well realize the bi-directional energy fluidity. The numerous controllers can be designed by MATLAB SISOTOOL easily and quickly. And PLECS software is used to validate the function of the propose...

In this work, an input-powered AC/DC CMOS bridge rectifier (CBR) is proposed using 0.18 μm CMOS process. It is based on a simple bridge connected full wave rectifier, without an external dc voltage to turn-ON. The rectifier may be used for energy harvesting applications with a typical output of relatively low-amplitude input and low frequency of ac voltages. The proposed CBR achieves a maximum ...
