摘要
介绍了基于DSP的三相航空变换器的设计原理和设计方法。采用电压型PWM整流器、高频链逆变器和周波变流器级联组合,使整机开关最大程度地实现了软开关,并可靠解决了周波变流器的"软换流"问题。试验结果表明,该变换器设计合理,具有较高的高功率因数和可靠性。
The design principle and method of aviation converter is proposed, by compounding the Three-phase voltage source PWM rectifier, high frequency link and cycloconverter, which make the circuit realize soft switching to the utmost extent and solve the problem current commutation of cycloconverter. The results of experiment verify the aforementioned control methods are right, more reliable, and high power factor.
