Overexcitation rectifiers with fast turn-off through voltage detection

The rectifier with built-in voltage sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer.
During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. The built-in voltage sensor ensures that the DC side output is interrupted when AC input voltage is removed.
The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. However, a separate power supply is required for the rectifier in the presence of driving loads, high moments of inertia or in case of frequency converter operation of the motor.
