FIELD: battery charging from single-phase or multiphase power supply with DC asymmetric current. SUBSTANCE: battery charger has controlled rectifiers, current-limiting sensors, variable resistor, valves, transformer with primary and secondary windings, rectifier built around diodes and capacitors, storage battery with discharge circuit, leads for connecting ac voltage supply, and control sources. EFFECT: provision for protection against overloads and short circuits and for automatic disconnection of controlled rectifiers. 8 cld
