Capacitive power supply
Abstract:
A capacitive power supply including an input section having input terminals for connection to an AC-mains supply, and a capacitive coupling, a rectification section coupled via the capacitive coupling to the input terminals, and an output section coupled to the rectification section, the output section including output terminals, for providing an output voltage to a load, a first chain including a charge storage facility, and a second chain arranged in parallel to the first chain, and including an output voltage limiting facility, the capacitive power supply further including an inrush current limiting facility, wherein the output terminals are connected to respective terminals of the output voltage limiting facility, and the DC-conducting series impedance has a resistive component with a resistive value of at least 0.2 times a resistive value of the first chain.
