Abstract
A power conversion device, comprising: an energization device (END) applying a voltage to armature and field windings of a rotating electrical machine (REM) according to an energization signal (ENS), and having inverter and alternator power generation modes (I-PGM, A-PGM); a power-generation switching signal generator (PGSSG) generating a power-generation switching signal (GES) for switching the I-PGM, A-PGM according to switching of a first selection (FSS) switching the modes arbitrarily and a second selection (SSS) switching the modes base on a maximum output in the modes; a voltage command generator (VCG) generating an armature voltage command (AVC) and a field voltage command (FVC) based on a REM output command (REMC); an energization signal generator (ESG) generating the ENS corresponding to armature and field windings based on AVC, FVC, GES and DC voltage of END, wherein PGSSG generates the GES by switching FSS, SSS regarding a rotating electrical machine output command MOC value.
