| Abstract: | A double forward zero voltage transition-pulse width modulation converter is introduced. The operating process of one switching cycle is analyzed in detail and the equivalent circuits in this switching cycle and some main switching wave forms are given. The technique of realizing soft switching is put forward. The disadvantages are discussed and some improving methods to the converter are presented. By using this soft switching technique, a prototype of aviation storage battery charger is developed, the block diagram of charger controller is presented and the principle of the charger is briefly described. Finally, the operating wave forms and some experimental results of charger are given. |
