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
