| 摘 要： | 针对传统全桥移相式零电压零电流开关(ZVZCS)PWM DC/DC变换器在实现滞后桥臂开关管零电流开关(ZCS)过程中,存在着辅助谐振电路附加损耗较大,软开关实现方式复杂,功率开关管电压应力和电流应力高等缺点,介绍了一种通过输出耦合电感实现软开关的全桥ZVZCS PWM DC/DC变换器。分析了该变换器实现软开关的原理,并采用LPC2214型ARM芯片作为控制器,设计了变换器数字控制系统。通过一台1kW,50kHz样机验证了这种软开关变换器相关理论的正确性。

| Abstract: | Conventional full-bridge Zero-Voltage and Zero-Current-Switching(ZVZCS) PWM DC-DC converters exist some disadvantages in the operating process of ZCS for lagging leg.These problems include additional losses in auxiliary circuit,complicated realization for soft-switching,and high voltage and current stresses of switches.A full-bridge ZVZCS PWM DC-DC converter with coupled output inductor was proposed to resolve these issues.The soft-switching operating principle of the converter was analyzed,and digital control system was designed using ARM chip LCP2214.An 1 kW,50 kHz prototype has verified the principle and characteristics of the proposed soft-switching converter. |
