ABSTRACT:
A detected DC voltage value estimation mechanism samples detected DC voltage values at specific intervals of a period T, stores detected DC voltage values Vnto Vn−mdetected at a present time tnup to a sampling time tn−mwhich is m sampling cycles (m≧1) before the present time tn, and calculates a DC voltage estimation value Vn+1at a next time tn+1using the detected DC voltage values Vnto Vn−m, expressing a curve connecting the voltage values Vnto Vn−mby a specific function. An output voltage control into which the DC voltage estimation value Vn+1is input corrects an output voltage command value and outputs the corrected output voltage command value to a power converter.
