This paper presents a simple two-loop voltage-mode control scheme for the buck converterwith input filter. In this voltage-mode control scheme the controller do not need any external saw-tooth generator for PWMgeneration and the loop design is also easier. The controller implementation requires only a single compensator in the outer loop and gives almost current-mode control performance. The proposed controller effectiveness is demonstrated through simulations using PSIM power electronics simulator.
