Abstract
A power inverter circuitis a bridge power inverter circuit comprising first and second switching elementssequentially connected in series between input terminals on higher and lower voltage sides and third and fourth switching elementssequentially connected in series between the input terminals on the higher and lower voltage sides and alternately turning on a set of the first and fourth switching elementsand a set of the second and third switching elementsso as to convert a DC power fed between the input terminals on the higher and lower voltage sides into an AC power. One of the sets of the first and third switching elementsand the second and fourth switching elementsis subjected to switching control at a frequency higher than that of the other.
