VOLTAGE ADDER IN ELECTRIC MAINS Russian patent published in 2014 - IPC H02M5/12 

FIELD: electricity.

SUBSTANCE: invention can be used mainly in countryside and suburb nursery gardens which power supply is made from transformer substations (TS) with rather long overhead power lines and at the ends of such lines mains voltage decreases to an unaccepted level thus deteriorating quality of services rendered by the energy service companies. The device consists of two bridge circuits with different conductivity direction for positive and negative alternating voltage half-periods respectively connected in parallel to the mains conductors, each of the circuits include two circuits of the in-series electrolytic capacitor and power transistor. Free outputs of capacitors in the first and second branches of each bridge circuit are connected to the phase and neutral conductors of the mains, at diagonal lines of the bridge circuits there are thyristors ensuring in-series connection of capacitors in each bridge circuit to the mains conductors in the second and fourth quarter-periods of alternating voltage respectively for the first and second bridge circuits and operational control of transistors and thyristors as per the set algorithm is carried out by a control unit for transistors and thyristors.

EFFECT: increase of voltage level.
