Abstract
A power supply system () is provided which comprises a first input (), an output (), a DC-DC converter (), a rectifying circuit () and a voltage limiter (). An AC voltage is received by the first input. Power is supplied to a load () via the output. The DC-DC converter comprises a second input () which is capacitively coupled to the first input, and the DC-DC converter provides power to the output. The rectifying circuit is capacitively coupled to the first input and is arranged between the first input and the output. The rectifying circuit provides a rectified output voltage to the output. The voltage limiter is coupled to the output and limits the rectified voltage to a predefined voltage.
