Abstract

Electric vehicle (EV) power trains need to interface low-voltage, high-current energy sources like fuel cells or batteries with high-voltage, low-current motors in an efficient manner. Especially when boosting or bucking is high, conventional single-stage, single-arm DC/DC converters frequently suffer from voltage instability, excessive component stress, and unfeasible charging/discharging topologies. In order to overcome these obstacles, this study investigates a multi-stage, multi-arm DC/DC converter that is intended to achieve a large voltage gain while minimizing ripples in voltage and current. For EV applications, a revolutionary high-gain battery/fuel cell powered DC/DC converter with a PI controller operating at 24V/600V is suggested. Three-stage interleaved input, comprising two cascaded stages and a third stage with a double float output that can handle bidirectional current, is a feature of the suggested architecture. The design and operating principles of 24V/600V battery powered DC/DC converter using PI controller is analyzed.
