VOLTAGE CONVERTER Russian patent published in 2014 - IPC H02M3/00 H02M3/335 

FIELD: electricity.

SUBSTANCE: device is composed of the following components: at least one power switch, to one output of which input voltage is applied, the other output is connected to the input of a transformer-rectifier assembly, at the output of which output voltage is generated, arriving to one input of a voltage divider and further via a comparison device to a summator, in which it is added to the signal of the first current sensor, connected in the circuit of the power switch, and arrives to the input of the control unit, comprising a width-pulse modulator and a current comparator, where the control signal is generated, arriving to the third output of the power switch. The transformer-rectifier assembly comprises the second current sensor, from the output of which the signal on the output current arrives to one input of the parallel operation assembly, the other input is connected to the output "PARAL", connected during parallel operation of sources of secondary power supply, and the outlet is connected to the other input of the voltage divider.

EFFECT: invention provides for operation of sources of secondary power supply in parallel mode with various sources of input voltage.
