KEY VOLTAGE STABILIZER WITH TRANSFORMER DECOUPLING Russian patent published in 2024 - IPC H02M3/337 

FIELD: converter technology.

SUBSTANCE: invention can be used in secondary power supplies, as well as in telecommunications equipment for power supply of energy-intensive devices with increased requirements for electromagnetic compatibility. The technical result is achieved by including the first and second pulse transformers, the first and second two-channel RDC circuits, and drivers made using a bridge circuit controlled by a phase-pulse converter. To expand the scope of application in terms of ensuring autonomy of use, a service rectifier, a service power supply unit and an additional secondary winding of the output transformer were introduced into the structure. The use of bridge driver circuits with transformer isolation and the introduction of a turn-on delay for transistors through RDC circuits directly in the key power amplifier channels increases the reliability of operation with very fast switching trajectories in conditions of simplified circuit solutions. The use of a special service power supply unit with support through an additional winding of the output transformer improves autonomy and expands the scope of application of the claimed device.

EFFECT: increasing reliability and simplifying circuit implementation.
