A capacitive power supply comprises
- an input section (10) with a first and a second input terminal ( Line, Neutral ) for connection to an AC-mains supply and a capacitive coupling,
- a rectification section (20) coupled via the capacitive coupling to the input terminals ( Line, Neutral ),
- an output section (30) coupled to the rectification section, the output section comprising
- a first and a second output terminal (V+, V-), for providing an output voltage to a load,
- a first chain comprising a charge storage facility (C2), and
- a second chain comprising a voltage limiting facility (D5) arranged in parallel to the first chain,
- the capacitive power supply further comprising an inrush current limiting facility (R1),
wherein the second chain includes a DC-conducting series impedance (Zdc) having a resistive component with a resistive value of at least 0,2 times a resistive value of the first chain. |
