Method for controlling converter for supplying electric drives e.g. in motor vehicles, has clock frequency of clock signal set for pulse width modulation depending on operating and/or environment parameters

摘要

A method for controlling a converter which generates an output AC voltage for supplying an electric drive in motor vehicle via pulse width modulation (PWM). A clock frequency (FSW) of a clock signal (P) for the PWM is set depending on the operating and/or environmental parameters to the smallest permissible clock frequency (SFW min zul).
