Abstract

PURPOSE:To increase the efficiency of a converter, by collecting the energy of the capacitor in a snubber circuit to a control power source. CONSTITUTION:An on-gate circuit 3 and an off-gate circuit 4 are provided to turn on a GTO (gate turn-off thyristor) 2 and turn off the GTO2, respectively. A snubber circuit 1 consists of a capacitor 11 and a diode 12, and the current flows through a closed circuit of the capacitor 11, the GTO2, a pulse transformer 43, a diode 6 and a reactor 5. Then the energy of the capacitor 11 is regenerated to a control power source via the transformer 43.
