Performance of Fly-buck DC-DC Converter using PI/PID-Based Controller for Applications in ElectricVehicles

The performance, design and control of a coupled inductor isolated buck DC-DC converter, fly-buck are discussed in this article. The recommended design enables an increase in the converter’s number of output voltages with the reduction of the voltage stress during switching. In this case, the linked inductor performs the transformer function for the isolated converter topology and the standard inductor function for the non-isolated section of the converter. The suggested isolated buck DC-DC converter, additionally referred to as the fly-buck circuit, is thoroughly examined for its characteristics and mode of operation. The described system is controlled using PID Controller and PI Controller; performance is also assessed using LT Spice simulation. It may be applied to industrial automation, intelligent electric metres, communication power supply, EV converters, and more.
