The invention relates to a circuit for the pulse width-modulated control of an electrical consumer, comprising a circuit part with a switching element for connecting and disconnecting the consumer to or from the source of the operating voltage in a clocked manner; a capacitor which is connected in parallel with said switching element and which is used as a buffer capacitor; and an electrical coil. The inventive circuit is characterised in that the circuit part that consists of the switching element and the capacitor lying parallel thereto is connected in series with the consumer and the coil, the capacity of the capacitor and the clock rate of the switching element being synchronised with each other so that the supply of operating voltage to the consumer is maintained independently of the position of the switching element. |
