FIELD: automatic control, possible use for bridge inverters with one-sided pulse-width modulation.
SUBSTANCE: in accordance to the invention, in the bridge inverter to generate output voltage it is enough to control condition of key elements of working diagonal only, and during modulation period, to control enabling and disabling of one of key elements, preventing occurrence of through currents, for even load of key element alternating method is claimed for disabling key elements of working diagonal.
EFFECT: prevention of through currents in key elements of bridge inverter, even load thereof and reduced dynamic losses.
