METHOD FOR REGULATING A CENTRE VOLTAGE

摘要

The invention, which relates to a method for regulating a centre voltage, is based on the object of specifying a method which implements simplified centre regulation, allows a reduction in the outlay of hardware and software components and hence can be used inexpensively. This object is achieved by measuring the intermediate circuit capacitor voltages and ascertaining the centre voltage from these measured voltages, and taking the position of the centre voltage as a basis for shifting the timing of the switch-on and/or switch-off edges of the switching voltage, the absolute value and direction of the shift being dependent on the position of the centre voltage.
