Abstract
A power converter and an operation method of the power converter are provided. The power converter includes a rectifier, a boost circuit, a current sensor, and a processor. The rectifier rectifies an AC power to generate a rectified power. The boost circuit includes a boost inductor. The boost circuit boosts the rectified power to generate an output power. The current sensor senses an inductor current value at the boost inductor to generate a sensed value corresponding to the inductor current value. The processor generates a first reference value according to an output voltage value of the output power, an input impedance value, and a first value. When the sensed value is greater than the first reference value, the processor enters a first operation mode to cause the sensed value to be not less than the first reference value.
