This paper presents the energy saving method by applying the voltage control\ntechnique on a single-phase AC source to a thyristor rectifier and an IGBT\ninverter with LC filter. Based on the LC filter parameter, the values of the gain\nfor the controller are obtainable. The proposed controller structure consists\nof two loops arranged in a cascaded model. The output of the first loop is the\ncapacitor current. This current is added to the load current in order to obtain\nthe current reference. This reference current value will be compared with the\ninverter current which produces the error signal to be fed into the second\nloop in the cascade system.
