Title:
CONVERTER CONTROL METHOD AND CONVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/040899
Kind Code:
A1
Abstract:
It is possible to control voltage after rectification according to power source voltage fluctuation without requiring a separate mechanism for detecting a wave height value of the power source voltage. A q-axis voltage instruction value (Vq*) is generated with an amount proportional to voltages (Vdc) at both ends of a smoothing capacitor (4). Assuming that the d-axis current instruction value (Id*) is zero, a d-axis voltage instruction value (Vd*) is generated according to it. According to the q-axis voltage instruction value (Vq*) and the d-axis voltage instruction value (Vd*), a pulse width modulation unit (605) performs pulse width modulation so as to generate a signal for controlling switching of a pulse width modulation converter (3).
