Title: Method and device for pwm modulation of multilevel inverter
Inventor: URUSHIBATA SHOTA
IPC: H02M7/49
Filed: 2016-10-11
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a frequency of an output voltage command cannot be made to be higher than a value specified by a carrier frequency if a level skip is prevented when a voltage command value of a multilevel inverter is generated.SOLUTION: A change rate switching function is arranged in a voltage command generation unit of a voltage command controller. The voltage command generation unit makes a limit value of an increase change rate of a voltage command value (final value) in a period when a carrier signal increases to be a value lower than a limit value of a decrease change rate of the voltage command value (final value). The voltage command value (final value) is controlled with the limit value of the increase change rate of the voltage command value (final value) in a period when the carrier signal decreases as a value higher than the limit value of the decrease change rate of the voltage command value (final value).SELECTED DRAWING: Figure 1
