Title:
POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2016046830
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve performance of a power conversion device.SOLUTION: The power conversion device includes a control section which controls an inverter through pulse width modulation control. In the power conversion device, the control section includes: cycle generation means for generating a pulse width modulation cycle on the basis of a reference cycle; division means for dividing a cyclic modulation range into a plurality of elements; sequence generation means for generating a pseudo random sequence by rearranging the elements; evaluation means for evaluating the pseudo random sequence; and signal generation means for generating a pulse width modulation signal on the basis of the pulse width modulation cycle and a predetermined pseudo random sequence.SELECTED DRAWING: Figure 1
