SECONDARY POWER SUPPLY SOURCE Russian patent published in 2022 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in devices for secondary power supply of radio engineering systems, automation and computer technology. The secondary power supply source contains a step-down single-cycle DC voltage converter (SDV), a feedback amplifier with a reference element, resistors, transistors, transformers, a generator, a demodulator, a comparator, a reference voltage source. At the same time, a resistor, a time-setting circuit, a control circuit, a rectifier diode, a transformer, a transistor, and a Zener diode are additionally introduced into the secondary power supply source. This made it possible to increase the reliability of the secondary power supply source by limiting the output voltage when any feedback element fails.

EFFECT: increasing the reliability of the secondary power supply source.
