CLOCKED VOLTAGE CONVERTER

摘要

The invention relates to a voltage converter (10) which is clocked in a regulated manner and has DC isolation and regulated adjustment of a number of output voltages (UAn) from an input voltage (UE) and has, on the input side, a semiconductor switch (12) controlled using a PWM device (13) and has, on the output side, a rectifier (14) and a desired/actual value comparator (20). A frequency-controlled desired value changeover means (30) changes over a first desired value (UAn) to a second desired value (UAn+1) associated with a currently selected operating frequency (fan) on the basis of an adjustable operating frequency (fan) of the PWM device (13), wherein the converter regulation or control means generates a control signal (SR, SD) from a desired value deviation and supplies said control signal to the PWM device (13) in order to adjust the currently selected output voltage (UAn).
