A dual gate drive circuit for a power converter and a control method are provided for reducing EMI of the power converter. The dual gate drive circuit comprises a switch and a switching control circuit. The switch is coupled to a transformer of the power converter to switch the transformer for regulating an output of the power converter. The switching control circuit generates a first switching signal and a second switching signal in response to a feedback signal to switch the switch for switching the transformer. The feedback signal is correlated to the output of the power converter. The second switching signal is enabled after a time delay once the first switching signal is enabled. |
