A new zero-voltage-switching (ZVS) DC/DC convertor which operates on constant frequency and has wide linearity is proposed. ZVS operations are achieved not only for the primary switches but also for the secondary rectifier diodes to reduce the switch stresses and losses. The proposed convenor also overcomes the other shortcomings of the conventional resonant DC/DC convertors such as high VA ratings of devices and passive components, load-dependent DC characteristics, etc.
