DEVICE FOR HIGH-SPEED CHARGING OF STORAGE BATTERY WITH ASYMMETRIC CURRENT Russian patent published in 2003 - IPC

FIELD: electrical engineering; battery charging using rectifier-inverter units. SUBSTANCE: device incorporating components that perform more than one function has control circuit using given algorithm and power section control circuit characterized in reduced number of components. Control unit in the form of single-chip microprocessor produces signals in compliance with algorithm for charging and synchronizing from supply mains to control bidirectional rectifier and bilateral switch. Storage battery connected to rectifier functions as its load. One of plates of each of current-limiting capacitors is connected to supply mains. Other plate of charging capacitor is connected to bidirectional controlled rectifier and other plate of discharging capacitor is connected to bilateral switch whose other end is connected to second plate of charging capacitor and to bidirectional controlled rectifier. Current limiting during charging and discharging periods enables rectifier control dispensing with phase control. EFFECT: reduced mass and size of device and simplified design of its power circuit. 1 cl, 1 dwg
