POWER CONVERTER CONTROLLING METHOD

摘要

A power converter controlling method suitable for a power converter is disclosed. The power converter is configured to output a power to a load. The power converter includes a switch. The power converter controlling method includes the following steps. The power outputted from the power converter to the load is detected and a switching frequency of the switch is adjusted according to the power. When the power is greater than a load threshold, the power converter is set to a first working mode, and the switching frequency of the switch is adjusted according to the power in the first working mode. On the other hand, when the power is smaller than or equal to the load threshold, the power converter is set to a burst mode, and the switching frequency is fixed at a setting frequency value in the burst mode.
