Abstract

The control technique presented in this paper -Peak Current Mode Control is a simplified power factor correction (PFC) technique for single stage AC/DC converters, By using low cost standard PWM control IC´s implementation becomes easy for this controller. In this paper Integrated buck-fly back converter (IBFC) is a single stage AC/DC converter, operating in discontinuous conduction mode (DCM) to achieve high Power factor with fast output voltage regulation. Comparative analysis of Peak current mode controller to hysteresis current controller for 90-230V input, 48V Output and 200W ac-dc converter operating at 100 kHz is presented and MATLAB/SIMULINK is used for implementation and simulation results show the performance improvement of proposed controller.
