The focus of this scope is on the single phase Cuk and SEPIC power factor correction converter that is attractive to electric bicycle applications. In order to guarantee improved performance, the proposed modified converter is designed to operate in discontinuous conduction mode, which is hidden by changes in supply and load voltage. For rated load, the investigational study achieves reduced input line total harmonic distortion and unity power factor. Line regulation, high efficiency, and load regulation are achieved by means of a closed loop PI control circuit that has a voltage sensor and current loop. The power supply is simulated using MATLAB/Simulink under various operating conditions, and the designed system is validated using a 250 W hardware prototype. The input current is observed to be perfectly sinusoidal, and the IEC 61000-3-2 class A standard is followed in recording the total harmonic distortion of the mains current.
