Abstract: A boost power factor correction circuit, a driving circuit for light-emitting diodes and a lighting device are provided. The boost power factor correction circuit includes: a PFC controller; a PFC switch controlled by an output of the PFC controller; and an equivalent variable resistor connected between the PFC switch and the ground. A feedback current input of the PFC controller is connected to a node between the PFC switch and the equivalent variable resistor. The resistance of the equivalent variable resistor is controlled by the output voltage of the PFC circuit. In case that the PFC circuit operates under an mains AC or CCG input, the resistance keeps constantly minimum, and in case that the PFC circuit operates under an ECG input, the resistance increases as the output voltage of the PFC circuit decreases. The boost power factor correction circuit, the driving circuit for light-emitting diodes and the lighting device according to the present disclosure are able to be compatible with mains AC, CCG and ECG power supplies.
