| Abstract: | A Zeta converter,known as zero voltage switching(ZVS) converter is introduced;the ZVS converter can increase efficiency and reduce the voltage stresses of power switch.When the converter operates in continuous mode(CCM),the switches can be turned on with zero voltage by using the resonance capacitor and the leakage inductor of the transformer.Operational principle of the converter is presented,and a specific circuit is designed and implemented to verify.The simulation results show that the efficiency of Zeta converter is 92.21% and the voltage ripple is 125 mV.It can be used in the field of the PDP power supply system. |
