The inverter is operated at a leading power factor, which requires the phase angle of the output current to be adjusted to each specific load point by the controller. The stable operation is verified by the experiments under the commutation inductance, 1.8µH, i.e., 18% reactance (130kHz, 250V, 30A base).
