Control circuit for AC inverter - has intermediate rectifier stage to control thyristor bridge circuit

The three phase inverter stage is designed to provide short circuit protection of the a.c. inverter thyristor stages. The unit has a mains rectifier stage that is sipplied from a three phase mains and supplies into smoothing circuit coupled to a chopper circuit. An oscillator circuit is connected to...

More Information
Summary:The three phase inverter stage is designed to provide short circuit protection of the a.c. inverter thyristor stages. The unit has a mains rectifier stage that is sipplied from a three phase mains and supplies into smoothing circuit coupled to a chopper circuit. An oscillator circuit is connected to supply clear pulses to an a.c. inverter circuit consisting of a thyristor bridge circuit. The output of the bridge provides a three phase supply for a load.
