This paper presents a new hybrid control method of asymmetrical half-bridge converter (AHBC) with low voltage stresses of the diodes. The proposed new control scheme can observe variation of secondary diode voltage stresses by using feedback of the input voltage and then decide the control portions, which are symmetrical control and asymmetrical control. Therefore, the proposed control scheme has many advantages such as a low rated voltage of the secondary diodes and low conduction loss according to the low voltage drop. The principle of the proposed control scheme is explained in detail and its validity is verifiedthrough simulated and experimental results

This paper presents a new hybrid control method of asymmetrical/symmetrical half-bridge converter (AHBC/SHBC) with low voltage stress of the diodes. The proposed new control scheme is executed by using feedback of the input voltage and then can decide operation of the converter is divided into two ranges, which are asymmetrical control and symmetrical control, So the proposed control scheme has many advantages such as a low rated voltage of the secondary diodes, and low conduction loss according to the low voltage drop. The proposed control scheme is verified by simulated results.
