谐振直流环节逆变器及其应用(Ⅰ)

Resonant DC Link Inverter and Its Application ( Ⅰ )

谐振直流环节逆变技术是实现单相和多相逆变器所有功率器件零电压开关的有效方法。本文讨论了谐振直流环节的基本工作原理,谐振直流环节逆变器的脉冲密度控制技术和谐振直流电压限制方法,并给出了实例。

Resonant DC Link Inverter RDCLI is an inverter in which all power electronic devices operate in zero voltage switching ZVS state. In this paper, the basic operating theory, the control method of pulse density modulation and the clamping circuit of DC resonant link voltoge are discussed.
