ABSTRACT:
An inverter has an inverter circuit and a current detector. In the inverter circuit, upper-arm switching elements and lower-arm switching elements, which are connected to DC power supply, provide DC with pulse-width modulation (PWM) so as to output AC to a load. The current detector detects current of the load. With the structure above, the inverter calculates an average value of DC that flows between the DC power supply and the inverter circuit according to a product of an ON-period in which any one of the switching elements maintains ON and a current value detected by the current sensor.
