摘要
本文以直升机舰面保障直流电源为研究对象,分析了移相全桥零电压PWM变换器工作原理,并建立了系统的数学模型。根据对模型的仿真,设计了变换器的控制参数并进行了试验,试验结果证明该设计方案是可行的。
The Shipboard DC Power Supply is investigated in the paper.The principle of ZVS PWM full-bridge converter is analyzed,and the model of the system is built. Base on the simulation of the model,the control parameters were designed and the power supply was tested.The experimental results show that the design scheme is doable.
