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

FIELD: electrical engineering.

SUBSTANCE: invention can be used in various power devices for electronic equipment. The voltage stabilizer comprises 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 comprises a resistor, an MIS transistor with an induced p-type channel. The reference voltage source comprises a resistor controlled by a programmable stabilitron. The output voltage divider comprises three resistors, one of which is variable. The first stage of the mismatch amplifier comprises a stabilitron, a resistor, a p-n-p-type bipolar transistor. The second stage of the mismatch amplifier comprises a resistor, an npn-type bipolar transistor, a pnp-type bipolar transistor. The protection unit comprises: six resistors; a pnp-type bipolar transistor; a MIS transistor with induced channel of n-type; two optocouplers, which are optocouplers of the LED-phototransistor type; a field-effect transistor with a control p-n-junction and a p-type channel; a diode.

EFFECT: expanding the functionality.
