CHARGING-DISCHARGING DEVICE Russian patent published in 2018 - IPC H02J7/34 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment, in particular to the autonomous objects power supply systems (PSS) using batteries as energy storage devices. Charging-discharging device comprising filters first and second capacitors, first and second MIS-transistors and first and second diodes, to increase the efficiency in the discharge mode by excluding the first high-frequency diode shunting by the MIS transistor low-frequency internal diode, further comprises third diode connected in series with the first MIS transistor, connected to the first transistor source by anode, and by cathode is to the second diode cathode.

EFFECT: proposed is PSS of autonomous objects.
