Abstract
A rectifying arrangement for an LED driver comprising a rectifying circuit and a clamping arrangement provides a low-impedance path between input terminals of the rectifying circuit in response to an abnormal operation of the rectifying arrangement, such as an open circuit of one rectifying branch of the rectifying arrangement. The low-impedance path is maintained for a plurality of cycles of an AC power supply provided to the rectifying circuit, and can be maintained on a (semi-)permanent basis.
