Abstract |
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 |
