Abstract
A newly designed universal converter is depicted for all forms of power conversions that include step-up and step-down operations. Universal operations include a rectifier, an inverter, a dc–dc converter, and ac voltage control operations in multi-input and multi-output circuits. The circuit consists of power switches such as six transistors, four thyristors, and two diodes, along with two inductors and two capacitors. The inductor role is important for step-up and step-down voltage levels from the source to the required output. In the existing converter, the number of switches is reduced from 26 to 12 in the proposed converter to obtain efficient operations. The circuit is initially developed in a MATLAB/Simulink platform by using a mathematical model and, finally, feasibility and effectiveness have been tested in the hardware test bench model. This converter is highly recommended for wind-solar-powered self-charging hybrid electric vehicles.
