METHOD AND DEVICE FOR SWITCHING SUPPLY VOLTAGE Russian patent published in 2025 - IPC H02M1/36 

FIELD: electronic equipment.

SUBSTANCE: method and device for switching supply voltage relate to electronic engineering and can mainly be used in special equipment. For example, in control systems and devices (subscribers) of spacecrafts (SC) for elimination of single starting pulse of current of devices. In particular, where in the circuits of the primary power supply of the spacecraft in order to increase the noise immunity of the system, the starting current of the subscriber with an amplitude that is much greater than the amplitude of the current of the subscriber in its normal operating mode is inadmissible. Proposed method consists in using aperiodic mode of capacitor charge accumulation as energy source W, providing formation of spacecraft subscriber starting pulse. Upon termination of the starting pulse, the subscriber switches to use of energy of the standard power supply of the spacecraft.

EFFECT: elimination of high-frequency interference when the subscriber is switched on in the circuits of the primary DC power supply, the absence of a starting pulse in the circuits of the primary power supply of the spacecraft, simplification of reclamation work; wherein starting load pulse current is generated as standard inside shielded housing of subscriber device.
