摘要：An arc suppression circuit (16) includes an insulated gate bipolar junctiontransistor (IGBT) (18) connected across the electrical switch contacts (10) to beprotected. When the contacts (10) open, the combination of added Miller capacitanceand the gate-to-emitter capacitance of the IGBT (18) results in the IGBT (18) turning on.
The IGBT (18) is quickly turned off thereafter by a second transistor (40), which turns onas the voltage across the suppression circuit rises following turn-on of the IGBT (18). Theturning on of the second transistor (40) results in the first power transistor (18) quicklyand abruptly turning off so that relatively little of the load energy is dissipated in thepower transistor (18).
