Design and Implementation of Closed Loop Soft Switching Boost Converter using PI Controller

Abstract

The design and implementation of closed loop soft switching boost converter have been proposed. The steady state analysis of open loop converter with operational modes are evaluated. Equations for the design of all the circuit parameters are attainted and discussed in details for simulation and experimental purpose. The main aim of this paper to maintain constant output at the converter end with variable voltage source. This is achieved by designing the PI controller as the feedback to the main circuit. The stability analysis of the proposed converter is done and improving the stability by designing the controller circuit and making the converter to operate in closed loop mode. The main advantage of this proposed converter is reduction in the swathing losses, current and voltage stress on the circuit parameter decreases, switching frequency increases. The simulation studies are done using a MATLAB software. And the hardware model is developed with the designed values.
