摘要: A zero-voltage switching DC/DC converter with the high circuit efficiency is presented in this paper. The structure of a full-bridge converter with the phase-shift PWM is used to achieve the zero-voltage switching in the transformer primary side for the purpose of the switching lose reduction. In order to increase the converter efficiency in the transformer secondary side, a current doublers rectifier, low current ripple, and synchronized rectifier circuits are also adopted. The detail circuit operation and mathematical analysis are presented in this paper. The measured efficiency on the prototype, a DC/DC converter 200V/24V with 6A output current, is higher than 88%.
