摘要：
A power supply system (200) is provided which comprises a first input (206), an output (218), a DC-DC converter (204), a rectifying circuit (212) and a voltage limiter (214). An AC voltage is received by the first input. Power is supplied to a load (216) via the output. The DC-DC converter comprises a second input (203) 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.
