DC-TO-DC VOLTAGE CONVERTER Russian patent published in 2019 - IPC H02M3/338 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to create systems of guaranteed power supply, electric drives of direct and alternating current, where an increase or decrease in the voltage of the primary direct current supply source is required. Claimed device comprises a single-phase transistor bridge inverter connected to a primary direct current supply source, two-winding transformer, bridge diode rectifier, to the input of which the secondary winding of the transformer is connected, voltage sensor, inputs connected to the outputs of the rectifier, microcontroller, to one input of which the rectifier voltage regulator is connected, to the other input – the output of the voltage sensor, driver, input of which is connected to the output of the microcontroller, outputs – to the control inputs of the inverter, the series-connected throttle and the capacitor are introduced, and connected to the middle points of the inverter arms, and the current sensor, whose input is connected to one of the circuits of the rectifier outputs, and the output – to the third input of the microcontroller, the primary winding of the transformer is connected to the capacitor.

EFFECT: technical result consists in concrete design of a single-phase bridge inverter for supplying a step-up or step-down transformer with one primary and one secondary winding followed by rectification of the alternating voltage of the secondary winding.
