MULTICHANNEL PULSE POWER SUPPLY SOURCE Russian patent published in 2025 - IPC G05F1/577 

FIELD: power electronics.

SUBSTANCE: invention relates to power electronics and specifically to pulsed secondary power supplies, and can be used to power microprocessor sets, high-integrity microcircuits, computer systems for aviation and space engineering. Multichannel pulsed power supply source comprises a driving oscillator unit, to which is connected at least one output voltages generating unit (OVGU), including multichannel comparator (400), multichannel pulse-width modulation (PWM) generator (500), multichannel error amplifier (600), multichannel driver (700) and voltage converter (800) comprising two independent transformers made on a common E-shaped core and connected to two output voltage lines.

EFFECT: use of the invention provides manufacturability of the multichannel pulsed power supply in terms of more efficient production due to reduction of labour costs for the manufacture of the product and better operational characteristics due to reduction of its dimensions and weight, simplified synchronization of conversion frequency for all output channels, possibility of creating one power supply with multiple output channels.
