VOLTAGE STABILIZER Russian patent published in 2025 - IPC G05F1/56 

FIELD: radio electronics.

SUBSTANCE: invention relates to radio electronics and can be used to build a power supply for powerful portable radio devices, for example, small-size unmanned aerial vehicles. Battery voltage stabilizer comprises a field-effect transistor, the drain of which is the input of the stabilizer and is connected to the battery, a first resistor, a second resistor connected to a common battery bus through two semiconductor diodes connected in series in the forward direction, a third semiconductor diode and a second field-effect transistor with an insulated gate and the same channel conductivity as the first field-effect transistor, wherein the drain of the second field-effect transistor is connected to the drain of the first field-effect transistor, the gate of the second field-effect transistor is connected to the connection point of the source of the first field-effect transistor and the output of the first resistor, third semiconductor diode is connected to the source of the second field-effect transistor, the second contact of which is the output of the stabilizer, wherein power of the second field-effect transistor and the third semiconductor diode correspond to the load current of the storage battery.

EFFECT: simplifying the implementation of addition of currents of two or more accumulator batteries with different degree of discharge in the load to increase the power of the loading radio device.
