CHARGING-DISCHARGING DEVICE Russian patent published in 2007 - IPC H02J7/02 

FIELD: electric engineering, in particular, electric supply systems for autonomous objects, in particular, spacecrafts.

SUBSTANCE: charging-discharging device contains first and second filter capacitors, first and second metal-dielectric-semiconductor transistors, throttle, while clamps of first filter capacitor are meant for connection of power supply and load, and clamps of second filter capacitor for connection of accumulator battery, while device is made on "n" one-type force cells, each containing also first and second metal-dielectric-semiconductor transistors, first and second filter capacitors, throttle, while clamps of first filter capacitor are meant for connection of power supply and load, and clamps of second capacitor of filter for connection of accumulator battery, in each cell in a chain of clamps of first and second filter capacitors, third and fourth metal-dielectric-semiconductor transistors are additionally coupled having same conductivity type and two current sensors with threshold device, output of first threshold device is connected to input of third metal-dielectric-semiconductor transistor, and output of second one is connected to input of fourth metal-dielectric-semiconductor transistor.

EFFECT: increased reliability of operation of charging-discharging device due to ensured protection of power supply circuits and accumulator battery from short circuits in individual cells.
