PULSED DC VOLTAGE CONTROLLER Russian patent published in 2014 - IPC H02M1/14 H02M7/155 H02M7/21 G05F1/56 

FIELD: electricity.

SUBSTANCE: pulsed dc voltage controller comprises series-connected first diode, controlled switch, filter inductance and load, two zero-diodes and filter capacitors, a microcontroller, a control driver, a feedback circuit and a manual control panel, a synchronisation unit, two inputs of which are connected to second unlike terminals of first diodes, and two outputs are respectively connected to inputs of the control driver and the microcontroller. The filter inductances are made on a common magnetic conductor and are magnetically coupled. The pulsed controller includes two additional capacitors and two second diodes. Each of the filter inductances is made with an additional lead. The leads of the additional capacitors are connected to additional leads of the filter inductances and the common terminal of the alternating current primary supply, respectively, and leads of the second diodes are connected to the additional and output leads of corresponding filter inductances.

EFFECT: enabling use to power self-contained inverters, cathodic protection stations, micro-arc oxidation apparatus and for powering various other electrical equipment.
