<p>A capacitive power supply comprises an input section (10) having input terminals(Ln, Nt) for connection to an AC- mains supply,and a capacitive coupling, a rectification section (20) coupled via the capacitive coupling to the input terminals (Ln, Nt),and an output section (30) coupled to the rectification section, the output section comprising -output terminals(V+, V-), for providing an output voltage to a load, -a first chain comprising a charge storage facility (C2), and -a second chain arranged in parallel to the first chain, and comprising an output voltage limiting facility (D5), the capacitive power supply further comprising an inrush current limiting facility (R1), wherein the output terminals (V+, V-)are connected to respective terminals of the output voltage limiting facility (D5), and the DC-conducting series impedance (Zdc) hasa resistive component witha resistive value of at least 0.2 times a resistive value of the first chain.</p> |
