Abstract

PURPOSE:To ensure the opposite polarity charge of a capacitor and thyristor's commutation by connecting a diode between a power source and a commutating transformer to interrupt the reverse discharge of a commutating capacitor. CONSTITUTION:When a thyristor SCR1 is turned on by triggering a thyristor SCR2 and by discharging the charging electric charge of a capacitor C, the discharging current flows into the circuits of Thyristor SCR2 Primary winding tP of a commutating transformer Diode D2 Power source E Resistor R Load transformer L Commutating capacitor C. In this case, a reverse current is cut off by the insertion of the diode D2, so the commutating capacitor C will by charged in opposite polarity up to the peak value of the resonnance voltage of the load transformer L and the capacitor C. Therefore, when the thyristor SCR1 is successively triggered, sufficiently big energy will be supplied from the capacitor C.
