SEMICONDUCTOR POWER CONVERSION DEVICE Russian patent published in 2017 - IPC H02M7/48 H02M7/527 H02M7/53846 H02P27/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in semiconductor power converters. A semiconductor power conversion device includes: a semiconductor power transducer (4), which performs power conversion using switching elements (42-1 - 42-6), and supplies power to the load (5); a unit (1) of calculating commands for the converter voltage control, which outputs a value Vref of the voltage control command that controls the semiconductor module (4) energy; a unit (2) of the voltage control, which applies the second voltage command value to the voltage command value Vref to generate the voltage command value Vref2; a unit (3) for PWM signal generating that generates a strobe signal for controlling the actuation of switching elements (42-1 - 42-6), based on the voltage control command value Vref2, and sends the strobe signal to the semiconductor power converter (4); and a shunting unit (6) that connects to the semiconductor power conversion device (4) parallel with the load (5) and branches the current with the frequency of the second voltage control command value from the output current Iout, which is issued from the semiconductor converter (4) to the load (5).

EFFECT: technical result is to improve the reliability of operation by providing the required current value.
