ABSTRACT:
A circuit arrangement in which an a.c. load is connected in series with a capacitor unit suitable for a.c. connection. In such a circuit arrangement, the use of capacitors suitable for d.c. operation is made possible by the fact the capacitor unit is made up of two polar capacitors which are connected in series with the load in such a way that the capacitors are interconnected with matching poles, either directly or by way of the load with matching poles, as well as by the fact that a rectifier diode is connected to each capacitor, with the cathode of the rectifier diode being connected to the positive pole of the respective capacitor and the anode being connected to the negative pole of the respective capacitor.
