抄録

This paper presents a novel half-bridge asymmetrical PWM DC-DC power converter based on the transformer secondary-side saturable-reactor assisted zero-voltage soft-switching principle, which can efficiently operate under conditions of stable zero voltage soft-switching PWM scheme for a widely-regulated load range as well as reduced conduction losses. The principle of steady-state converter operation is illustrated including its approximate circuit analysis. Moreover, a 200KHz-150W prototype soft-switching PWM power converter with a high-frequency transformer link is implemented and evaluated to demonstrate its practical effectiveness on the unique operating performances mentioned above.
