Original Abstract Submitted
An electromagnetic interference suppression method for at least one power supply is provided. Each of the at least one power supply includes a first conversion circuit and a second conversion circuit. The first conversion circuit receives an input voltage and outputs a first output voltage. The second conversion circuit receives the first output voltage and outputs a load current. If the input voltage received by the first conversion circuit of the at least one power supply is a DC voltage, an electromagnetic interference suppression operation is performed. Then, the electromagnetic interference suppression operation is performed to determine whether the load current is greater than a preset current and lower than an upper current limit. If the determining condition is satisfied, the first output voltage is dynamically adjusted, and a peak-peak value of the first output voltage is not zero with the varying load current.
