... current with a controllable power factor in contrast to the turn-on and turn-off timing by using possessing high- conventional LCI system. It is achieved that the total harmonic frequency switching devices such as MOSFETs and IGBTs distortion (THD) of the injecting currents for the different [3]. The total losses of this inverter are ...
