This paper proposes the design of power factor correction (PFC) boost converter circuit and phase-shift full-bridge (PSFB) inverter circuit for electric vehicle (EV) battery charger. The proposed circuit uses single-phase AC source that its structure includes two main circuits are PFC boost converter and PSFB inverter. The study of these circuits designed uses simulation by MATLAB application and actually experiment with the circuit power of 3.2 kW. From the simulation and experimental results illustrate that PFC boost converter part can control the input AC current source to be a sine wave and in-phase with input AC voltage source by using 100 kHz switching frequency. For PSFB inverter part controls by adjusting the phase-shift of gates signal by using 30 kHz switching frequency and it can control the output DC voltage from 0-380V with 9A current.
