A new hybrid control current-doubler-rectifier ZVS PWM three-level half-bridge DC converter is proposed

it has the following characteristics: ①The four switches on the primary side are divided into two groups

in the same group

the drive signal of one switch leads or lags 180℃ each other

however

it is complementary when compared with the drive signal of the corresponding switch in another group.②ZVS is achieved for all switches in a wide load range with the use of the energy in the output filter inductors.③The output rectifier diodes commutate naturally without voltage oscillations and voltage spike.④The proposed converter can realize self-drive of synchronous rectifier conveniently.The principle of the proposed converter is analyzed and the simulation results are given to prove the correctness of the theory analysis.
