Fuzzy Logic Controller based Implemented ZVT-ZCT PWM Boost Converter using Renewable Energy Source

In this study, a new boost converter with an active snubber cell is proposed. The active snubber cell provides main switch to turn on with zero voltage transition (ZVT) and to turn off with zero current transition (ZCT). The proposed converter incorporating this snubber cell can operate with soft switching at high frequencies. Also, in this converter all semiconductor devices operate with soft switching. There is no additional voltage stress across the main and auxiliary components. The converter has a simple structure, minimum number of components and ease of control as well. The Fuzzy Logic (FL) controller with two inputs maintains the load voltage by detecting the voltage variations through d-q transformation technique that is connected in feedback of these converter. The operation principle and detailed steady state analysis of the Fuzzy based ZVT-ZCT-PWM boost converter is given. The presented theoretical analysis is measured in simulation results by 1kW converter. Here output power upto 400v is given Also, the overall efficiency of the new converter has reached a value of 97.8% at nominal output power.
