摘要: A PI control section performs a PI control on a deviation which is a difference between a DC voltage command and a DC voltage, and outputs a d-axis current command value. A PI control section performs a PI control on a deviation which is a difference between the d-axis current command value and a d-axis current, and outputs a d-axis voltage command value. Based on the d-axis voltage command value and a q-axis voltage command value, a PWM control section outputs a switching control signal for controlling a switching operation of a converter. A voltage command computation section generates the DC voltage command based on the d-axis voltage command value.

摘要: A power converter is provided with a rectifying circuit, an inverter circuit, and a common mode filter including a common mode choke coil and a capacitor. The switching frequency of a PWM rectifying circuit is set at three times the switching frequency of a PWM inverter. Alternatively, the resonance frequency of the common mode filter is set at twice the carrier frequency of the rectifying circuit or the PWM inverter circuit or more.

摘要: Switching control is remarkably simplified and a DC voltage is boosted, and then, an input power factor is sufficiently improved and harmonics are reduced by connecting a full-wave rectifier circuit to an AC power source through a reactor, and connecting a smoothing capacitor and boosting capacitors, which are connected in series with each other, in parallel between the output terminals of the circuit. In addition, a switching device is connected between the input terminal of the circuit and the connecting point between the boosting capacitors, and a control device is provided to control the switching device so that the switching device can be switched at every half cycle of the power source voltage.
