Closed Loop Controlled Double Forward Converter Analysis Using PI, Fuzzy logic and ANN Controller

Abstract

Closed loop controlled DC to DC double forward converter is a requisite for the server SMPS system. High efficiency, Isolation, Steady state voltage, Transient response, High switching frequency, reduced noises and range of steady state are all necessary requirements for the double forward converter. In this paper, a 40 V double forward converter for charging the battery of server SMPS is proposed. Simulation of closed loop controlled DC-DC double forward converter using proportional integral (PI) controller, fuzzy logic controller (FL) and artificial neural network controller (ANN) converter are simulated, analyzed and discussed. In this paper, from comparison of performance in the closed loop model by using the three controllers, a suitable converter is proposed for the sever SMPS system. The proposed circuit achieves steady state voltage, when the disturbance occurs. Its circuit operation in closed loop control model and the performance of the double forward converter is described and the simulation results are presented.
