Abstract

An Isolated ZVS/ZCS bidirectional DC-DC converter for DC Uninterruptable Power supplies is presented in this paper. The usual way to avoid a computer shutdown during the mains failure is to connect an ac uninterruptible power supply (UPS). Alternatively, in this paper, a simple and high efficiency dc UPS is presented by an isolated bidirectional soft-switching dc-dc converter. The bidirectional dc-dc converter operates under zero-current switching (ZCS) /Zero voltage switching conditions by utilizing the leakage inductor of the transformer. ZVS/ZCS operation is achieved in battery-backup and charging modes, which significantly reduces the power losses in the bidirectional converter. The principle of operation is analyzed and simulated by using MATLAB simulink.
