Title:
POWER CONVERSION DEVICE, POWER CONVERSION DEVICE CONTROL METHOD, ROTATION SENSORLESS CONTROL DEVICE, AND ROTATION SENSORLESS CONTROL DEVICE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/192373
Kind Code:
A1
Abstract:
A setting unit of a power conversion device of an embodiment sets duration time at random and sets one of a plurality of carrier wave frequencies different from each other as a set carrier wave frequency. This allows a carrier wave generation unit to generate a predetermined carrier wave having the set carrier wave frequency for a predetermined duration time. A PWM signal generation unit then generates a PWM signal on the basis of the carrier wave generated by the carrier wave generation unit. A power conversion unit performs a power conversion on the basis of the generated PWM signal and supplies the converted power to a load.
