FIELD: electrical engineering; charge-discharge rectifier-inverter converters for storage batteries.
SUBSTANCE: proposed device has control circuit using desired algorithm and power section control circuit. Control unit in the form of single-crystal microprocessor generates signals in compliance with charge algorithm and supply mains synchronization for controlling balanced controlled rectifier, balanced switch, and discharge capacitor value. Storage battery is connected to rectifier as load. One of current-limiting capacitor plates is connected to supply mains. Other plate of charge capacitor is connected to balanced control rectifier and other plate of discharge capacitor, to balanced switch whose other lead is connected to second plate of charge capacitor and to balanced control rectifier. Current limiting during charge and discharge period makes it possible to control rectifier dispensing with phase control.
EFFECT: ability of controlling amplitude ratio of charge and discharge pulses.
