摘要：A control apparatus controlling a rotating machine includes a signal output unitthat outputs an excitation signal to a resolver used for detecting a rotational angle of the

rotating machine; a demodulation unit that demodulate a signal related to the rotationalangle based on a detection of a modulated signal and the excitation signal so as tooutput a demodulated signal; a filter that eliminates higher harmonics in the

demodulated signal outputted by the demodulation unit so as to output a calculatedangle of the rotational angle; and an operating unit that controls a switching elementincluded in a DC-AC conversion circuit to be ON and OFF based on the calculated angle ofthe rotational angle outputted by the filter, so as to control the rotating machine with anoutput voltage of the DC-AC conversion circuit supplied to the rotating machine.
