This paper proposes the improvement commutation circuit that is able to decrease commutation loss at no-load and light-load and commutate at step load variation. As the consideration result of operation characteristics, we confirmed that operation characteristics are equal to theory. Also, if we use recovery period of side diode by reverse bias of main thyristor, it increase storage charge utility factor of commutation capacitor.
