FIELD: charging storage batteries with DC or asymmetric current from three-phase ac mains. SUBSTANCE: charger has controlled valves, current sensors (limiters), controlled resistors, transformer, additional transformer, rectifier, and discharge circuit, and also leads for connecting control source and multiphase power supply, reactor, or sensor control leads of controlled resistors, additional control input, additional sensor or indicator, or control source. EFFECT: improved circuit arrangement. 10 cl, 1 dwg
