BATTERY CHARGING AND DESULPHATION DEVICE Russian patent published in 2024 - IPC H02J7/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to devices for charging accumulators with asymmetric current. Device additionally includes a voltage amplifier on one bipolar transistor for controlling a power switch located separately from the multivibrator, in order to stabilize the asymmetric current parameters, in addition, the multivibrator unit further includes logarithmic circuits to reduce the duration of pulse fronts and a diode to reduce noise on the multivibrator; as well as a device for implementing the possibility of alternation of alternating and direct voltage sources additionally includes two input terminals for connecting the solar battery and voltage stabilization units – for additional protection during charging from the solar battery, besides, the charging circuit additionally includes a switch and a resistor to select a power source: an alternating voltage network or a solar battery.

EFFECT: improved stabilization of asymmetric current parameters and possibility of alternation of alternating and direct voltage sources.
