POWER SUPPLY WITH TWO AC AND DC INPUTS AND PROGRAMMABLE DC OUTPUT USING SECONDARY STEP-DOWN CONVERTER Russian patent published in 2006 - IPC H02M1/10 

FIELD: electrical engineering.

SUBSTANCE: proposed power converter 10 with two dc/ac inputs has dual input 12, 14 used to receive both dc and ac input voltage and with selectable dc output 16, as well as second dc input 18. Power converter 10 has power-converter circuit 20 incorporating ac-to-dc converter 22, step-up dc converter 24, feedback circuit 26, filter circuit 25, and dc converter 28. Power converter 10 makes it possible to solve many problems for organizing system operation related to use of complete set of various interface components required for feeding mobile facilities of all kinds from ac or dc power supply. In addition, power converter 10 also has two output-voltage leads 16, 18 enabling power supply to plurality of different mobile facilities from single converter.

EFFECT: enlarged functional capabilities.
