VARIABLE FREQUENCY MODULATION TECHNIQUE OF INVERTER

摘要

The present invention relates to a variable frequency modulation technique and, more specifically, to a variable frequency modulation technique which increases a switching frequency when a slope of an output voltage order value of an inverter is larger than a predetermined slope and which lowers a switching frequency when the slope of the output voltage order value of the inverter is larger than the predetermined slope so as to reduce a switching frequency, thereby improving efficiency of the inverter.;COPYRIGHT KIPO 2017
