摘要:Full Bridge (FB) DC–DC converter is an attractive topology for high power level applications. Pulse Width Modulation (PWM) current-fed full bridge dc–dc step-up converters are typically used in applications where the output voltage is considerably higher than the input voltage. In this paper, a comparison is made between two converter topologies of this type—the standard Zero-Voltage Switching (ZVS) active-clamp topology and a new Zero-Current Switching (ZCS) topology. This paper begins with a review of the operation of the ZVS active-clamp converter and that of ZCS converters in general; the advantages and disadvantages of each approach are stated. A new ZCS-PWM current-fed dc–dc step up full-bridge converter is then introduced. Finally, a comparison of the performance of the two converters is made and conclusion based on this comparison is stated. Finally the full bridge DCDC buck converter is simulated with the help of MATLAB simulink.
