Abstract
An inverter device made detectable at a high speed and highly precisely a load voltage of all waves in one cycle, with an arrangement including a voltage detecting means having a capacitor and connected to a load which is connected through a switching means to a DC power source, means connected to the voltage detecting means for charging and discharging the capacitor, and means for maintaining, in a predetermined period in which a transient voltage upon every inversion of load voltage is generated, a capacitor voltage immediately before the predetermined period.
