An operating resonant load circuit, a dimming circuit and a dimming method are disclosed. The operating resonant load circuit includes: an input unit including a plurality of input terminals, for receiving an AC voltage; a rectifier, for transforming the AC voltage received by the input unit into a DC bus voltage; and a controller, for dividing the DC bus voltage based on an conducting status of the input terminals to output a corresponding DC reference voltage. The dimming circuit and dimming method use the operating resonant load circuit to perform dimming.
