摘要： In order to limit an overvoltage at a parallel circuit of IGBT (3) and freewheeling diode (7), an undesirable current spike is used to switch on the intrinsically turned-off IGBT (3′) during the presence of the current spike precisely to an extent such that a current which counteracts the overvoltage arises in the IGBT/freewheeling diode pair. The oppositely acting current reduces the current gradient in leakage inductances (Lσ) and reduces the undesirable induced overvoltages.

摘要： A wide input voltage range relay drive circuit allowing a more than 2:1 input voltage variation is provided. The circuit utilizes a scaled and rectified bulk voltage to drive the relay coil. As the monitored bulk voltage increases beyond the relay coil rated voltage, the circuit pulse width multiplexes this bulk voltage to protect the relay coil. The bulk voltage switching does not begin, however, until the relay energizes. To reduce the power dissipation during the PWM switching, of the relay coil, a power dissipating switch is included and held on during the PWM switching events. To further increase relay life, the circuit controls the energizing of the relay coil to actuate the contacts of the relay at or near a zero cross of the power switched thereby.
