PURPOSE:To readily calculate the output of an inverter by detecting the average value of the rectified value of an input AC current, equivalently obtaining the average value of the DC currents from them, and multiplying the average value by the output side DC voltage. CONSTITUTION:An input AC current is detected by a current detector 6, the output of which is rectified by a rectifier 7, further smoothed by a filter 8, and applied to a multiplier 10. The output DC voltage of a rectifier 2 is detected by a voltage detector 9, and the output is applied to a multiplier 10. The multiplier 10 multiplies the output of the rectifier 7 by the output of the detector 9. The output of the multiplier 10 corresponds to the output signal of an inverter. |
