摘要：Disclosed are an alternating current rectifying circuit and an alternating currentrectifying method for driving an LED module. The method comprises: when an alternatingcurrent module is in a positive half cycle, after an alternating current output by thealternating current module is rectified, outputting the alternating current to a positivehalf cycle rectifying branch circuit of an external LED module; when the alternatingcurrent module is in a negative half cycle, carrying out charging according to thealternating current output by the alternating current module, and when the alternatingcurrent module is in the positive half cycle, carrying out discharging, and outputting thealternating current to a positive half cycle feed branch circuit of the external LED module;when the alternating current module is in the negative half cycle, rectifying thealternating current output by the alternating current module, and outputting thealternating current to a negative half cycle rectifying branch circuit of the external LEDmodule; when the alternating current module is in the positive half cycle, carrying out

charging according to the alternating current output by the alternating current module,and when the alternating current module is in the negative half cycle, carrying outdischarging, and outputting the alternating current to a negative half cycle feed branchcircuit of the external LED module. By using the present invention, stability of an outputvoltage can be improved, and luminous efficiency of the LED module can be improved.
