FIELD: electricity.
SUBSTANCE: power supply system comprises solar battery (SB), accumulator battery (AB), voltage regulator and discharge device made as bridge inverters. Charge device, two separate matching transformers, control system with optimised power control, load with different feed voltage rates. SB is connected to voltage regulator, which output is connected to primary winding of the first transformer. AB is connected to discharge device, which output is connected to the first winding of the second transformer and to charge device, which input is connected to secondary winding of the first transformer. Secondary windings of the first and second transformers are coupled in series and feed the load through rectifier.
EFFECT: improved energy efficiency due to implemented optimised power control both in AB charge mode and in the mode of on-board load joint power supply from SB and AB.
