Implementation of ZCT PWM Converters for Renewable Energy Applications

Abstract

In this paper an improved two types of ZCT PWM buck DC-DC Converter is proposed. Also a comparative analysis is structured between the conventional ZCS and the proposed ZCT PWM converters. The Conduction duty cycle is increased step by step for both the ZCS and ZCT PWM converters and respective results are tabulated for the power and loss comparison. The proposed converter generates reduced switching loss and increased efficiency than the conventional ZCS PWM converter. Additionally, a closed loop approach is also done for both the ZCS and ZCT PWM DC-DC converters using the PI controller design. All the simulation works are carried out under the MATLAB SIMULINK environment at a frequency rate of 10 kHz.
