摘　　要：介绍了基于DSP＋CPLD的115V／400HZ三相逆变电源的设计原理和设计方法，采用移相谐振控制技术和周波变流型高频环节逆变技术，使整机开关最大程度地实现了软开关，并可靠解决了高频脉冲变压器漏感储能引起的电压尖峰问题。实验结果表明，该逆变电源设计合理、可靠性高，并在小型化、提高功率密度和可靠性方面取得了很好的效果。A design method of three-phase inverter aerial power of115V/400Hz based on DSP＋CPLD is proposed, by including the phase-shift-controlled technology and the high-frequency （HF） link inverting technology,which makes the circuit realize soft switching to the utmost extent and solve the problem of peak voltage caused by the storing energy of leakage inductance of HF transformer reliably. The results of experiment verify the aforementioned control methods are right, more reliable, and bring the system with small volume and weight, high reliability and power density.
