A zero voltage switching(ZVS)Zeta converter with asymmetrical PWM control is presented.By discussing its different operating processes in CCM mode,the characteristic of ZVS and the steady-state equations are analyzed.Then a novel driving and control circuit for this converter is proposed.It includes complementary PWM signals generating circuit,floating gate voltage driving circuit of power MOSFETs,the sampling and feedback circuits which is applicable for the high voltage output.Finally,a practical power supply with output of 200 V/1.5 A is applied to the proposed convener and driving circuit.The experimental results verify the validity and feasibility of the circuit.
