THYRISTOR CHOPPER WITH CAPACITORS IN POWER CIRCUIT Russian patent published in 2008 - IPC H02M7/525 

FIELD: electricity.

SUBSTANCE: device is supplied with a block of expanding of the range of regulation, executed on the principle of the transfer of the electric energy saved up in inductance from the source to the receiver. Thus the energy source is the additional winding of the transformer, and using the filter capacitor shunting the power supply.

EFFECT: realisation of pulse-frequency regulation of a current load in all ranges of loads from zero up to maximum with rigid and linear external characteristic.
