摘　　要：目前,某型特种车辆中三相400 Hz中频电源仍采用电动机-发电机模式,具有体积和重量大、噪声大、效率低的缺陷。这里采用高频功率变换技术成功研制了一台200 W/36 V三相中频电源,其主电路采用两级功率变换方式,首先通过推挽正激电路将车辆直流24 V转换为较高的电压,再通过三相H桥逆变电路和二阶LC滤波电路得到所需的三相36 V交流线电压。理论分析和试验表明,设计的中频电源具有体积小、重量轻、无噪声、效率高的优点。Three phase 400 Hz mid-frequency power supply is used in a special vehicle.It still adopts the mode of motor-generator which has the disadvantages of higher volume,higher weight,big noise and lower efficiency.This paper designs a 200 W/36 V three phase 400 Hz mid-frequency power supply by using high frequency power converting technique.Its main circuit includes two level power convertors.The first level realizes the converting 24 V DC to a higher DC voltage.The second level converts the higher DC voltage into three-phase AC by using three-phase H bridge and LC filter.Theoretical analyzing and experiments show that the designed 400 Hz mid-frequency power supply has the merits of light volume and weight,no noise,higher efficiency.
