TWO-CHANNEL POWER SUPPLY SOURCE Russian patent published in 2015 - IPC G05F1/577 G05F1/563 G05F1/585 

FIELD: electricity.

SUBSTANCE: two-channel power supply source comprises a regulating field transistor, the drain of which is connected to a diode anode and the first output of the first throttle winding, the second output of which is connected to the first inlet of the source, and the source is connected to the second inlet combined with a common output. A key element is introduced, the control inlet of which is the control inlet of the two-channel source, and outlet outputs are connected between outputs of the first and second channels. The second throttle winding is connected to a half-bridge rectifier, the first outlet of which is connected to the output of the second channel, and the second outlet is connected to the common output. The outlet divider is connected to the outlet of the first channel and the common output of the two-channel source, and by a medium point - to the inlet of the control unit, the outlet of which is connected to the gate of the regulating field transistor. The outlet divider comprises a stabilitron, resistors and a transistor, the base of which is connected to the output of the second channel of the two-channel source of power supply.

EFFECT: possibility to vary and stabilise voltage at the outlet of the second channel with stable outlet voltage at the outlet of the first channel of the two-channel power supply source.
