Novel Three-Phase Resonant DC Link Inverter
In order to achieve high efficiency operation of three-phase inverter, a novel topology of the three-phase resonant DC(Direct Current) link inverter is proposed, in which a simple auxiliary resonant circuit is set up in the DC link. The working flow of the circuit is analyzed. The experimental results show that the switching device achieves soft switching and the output current waveform of the inverter has no obvious distortion Therefore, the inverter can realize high-efficiency and stable operation.
