In order to improve the input voltage range of the active clamp forward (ACF) converters and reduce the input current of the transformer primary coil, this paper proposes a ACF converter circuit with Boost-Buck integration. Firstly, the operating process of this converter is analyzed, the circuit parameter design is given out, next, and finally, the simulation is performed using Saber software. Simulation results show that this proposed circuit can realize the integration function of the primary voltage step-up and the output voltage Boost-Buck, and this converter can improve effectively the input voltage range, reduce the input current of the primary coil, and realize the integration function, thus verifying the validity and feasibility of the circuit.
