  • High forward blocking voltage protection circuit
    Patent number: 4937726
    Abstract: To protect a semiconductor switch from high forward blocking voltage stresses during turn-off, a relief circuit is provided comprising a diode and a capacitor. The energy generated when the semiconductor switch is turned off or switched to the non-conducting state, is temporarily stored in the capacitor of the relief circuit until the semiconductor switch is changed back to its conducting state. Then the energy stored in the capacitor is transferred to a useful impedance by means of a further semiconductor switch being changed to its conducting state.
