FIELD: automatic control, possible use for bridge inverters with two-sided pulse-width modulation.
SUBSTANCE: in the bridge inverter to generate output voltage it is enough to control condition of key elements of working diagonal only, and on modulation period, to control enabling and disabling of one of key elements, preventing occurrence of through currents, for even load of key elements an alternating method is suggested for disabling key elements of working diagonal.
EFFECT: prevented through currents in key elements of bridge inverter, possible even loading thereof, reduced dynamic losses when switching key elements.
