REGENERATOR OF SINGLE-PHASE VOLTAGE IN NETWORK Russian patent published in 2015 - IPC G05F1/00 

FIELD: electricity.

SUBSTANCE: invention suggests regenerator that comprises transformer 1 with secondary winding 2, to which double-pole rectifier 3 is connected, and the winding is connected to terminals 4 of network voltage. The transformer comprises secondary windings 5, and each of them is connected to the respective rectifier 6. Key cascades 7 are connected to rectifiers 6, and each cascade consists of two keys 8 and 9 and key control scheme 10. Inputs of key control scheme 10 for each key cascade 7 are coupled to the respective outputs of reversible counter 11. The first key cascade 7 is coupled to key elements 12 and 13, which together with key elements 14 and 15 create a bridge circuit. Connection point of key elements 14 and 15 is connected to mid point of double-polar rectifier 3. Connection points of key elements 12-14 and 13-15 form output of the regenerator, to which load 17 is coupled through protective unit 16. The regenerator also contains power amplifier 18, comparator 19, comparator 20, resistive divider 21, reference signal generator 22 consisting of generator 23 generating sinusoidal signal, comparator 24, controlled follower 25 and key 26, control circuits 27 and 28 for key elements 13 and 14, inverter 29, control circuits 30 and 31 for key elements 12 and 15.

EFFECT: receiving signal of sinusoidal shape close to ideal sinusoid, providing potential frequency adjustment for output voltage and increasing efficiency factor.
