VOLTAGE STABILIZER Russian patent published in 2023 - IPC G05F1/569 

FIELD: electrical engineering.

SUBSTANCE: various power devices for radio electronic apparatus. The voltage stabilizer contains a control element, a reference voltage source, an output capacitor, an output voltage divider, the first stage of the mismatch amplifier, a separating diode, the second stage of the mismatch amplifier, a protection unit. The regulating element contains a resistor, an MIS transistor with an induced p- type channel. The reference voltage source contains a resistor controlled by a programmable stabilitron. The output voltage divider contains three resistors, one of which is variable. The first stage of the mismatch amplifier contains a stabilitron, a resistor, a p-n-p- type bipolar transistor. The second stage of the mismatch amplifier contains two resistors, two n-p-n-type bipolar transistors. The protection unit contains eighteen resistors, a p-n-p-type bipolar transistor, an operational amplifier, two diodes, three n-p-n- type bipolar transistors, two optic couplers, which are an optic coupler of the LED-phototransistor type, a field transistor with a control p-n- junction and a p- type channel.

EFFECT: expanding the functionality.
