Abstract (en)

[origin: DE19725708A1] The invention relates to a method for controlling at least two electrical consumers in a single circuit arrangement with pulse width modulated signals. According to the invention, a supply current which flows during the pulse pause of said pulse width modulated signals and is dependent on an inductor of the electrical connection lines is taken up by a buffer capacitor. The pulse width modulated signals are generated with time delay.
