Abstract:
A phase adjustment circuit of a power converter, the power converter, and a control method of the power converter are provided. The control method includes following steps. A delay signal is generated according to an error signal, and the error signal is associated with an output voltage of the power converter. A difference between the error signal and the delay signal is amplified. A control signal is provided according to the amplified difference and the error signal, and a phase of the control signal leads a phase of the error signal. The control signal serves to improve a response speed of the power converter.
