Digitally controlled Active Clamp Forward Converter with small signal discrete-time modeling

In this paper the Small Signal Discrete-time Model for Active Clamp Forward Converter is proposed by using state space averaging technique to design a digital controller, takes in to consideration of modulator effects and delays in the control loop. The validity of the designed model and achievement of desired compensation for Active Clamp Forward Converter with digital controller is confirmed by the results of the MATLAB simulation by using digital redesign method. Finally simulation results are presented and analyzed for 5V, 100W Active Clamp Forward Converter with Discrete-time controller.
