Abstract :
The actively clamped resonant DC link inverter (ACRDCLI) has the advantages of low switching losses and relatively simple topology. Its disadvantages are its high currents and high losses in the resonant inductor and in the clamp device. In order to decrease the losses in the resonant inductor and in the devices, a novel two amplitudes scheme is presented here. Various simulation waveforms and experimental results show that the two amplitudes actively clamped resonant DC link inverter has a good output current and the losses in the resonant inductor and in the clamp device are much lower than the traditional actively clamped resonant DC link inverter
