COMPACT VOLTAGE CONVERSION DEVICE WITH CONTINUOUS OUTPUT RANGE OF REGULATION Russian patent published in 2017 - IPC H02M3/158 

FIELD: electricity.

SUBSTANCE: invention relates to a voltage conversion device (10) for supplying a load (11) with a PWM signal via an inductive output filter (105). The voltage conversion device (10) comprises a voltage conversion module (101), powered by a DC input voltage (Vin), and is configured to provide a plurality of output signals (PWM1, …, PWMn) with an amplitude level that is a fraction of the input voltage level (Vin). Each output signal fluctuates within a bias voltage component divided into a plurality of levels in the range from the set smallest amplitude level fraction to the set largest amplitude level fraction. The voltage conversion device (10) further comprises a multiplexer (103) receiving the set plurality of outputs (PWM1, …, PWMn) as a plurality of inputs. The multiplexer is designed for output of one output signal (PWMx) selected from a plurality of inputs, wherein the output signal (PWMx) of the multiplexer (103) is connected to the output filter (105).

EFFECT: increased compactness.
