Abstract: A control circuit of a power converter including a first and a second control modules is provided. The first control module sets sampling points for a ripple signal of an input voltage according to a reference signal. The first control module determines whether a power point is the maximum power point according to ripple voltages of the sampling points. The second control module controls the power converter to output a maximum power according to the maximum power point based on the determination result of the first control module and the reference signal. An embodiment of a method for tracking a maximum power point is provided. The input voltage of the power converter is measured. The sampling points are set for the ripple signal of the input voltage and phase information of the ripple signal is determined, such that the maximum power point is determined by using the ripple voltages.

Abstract: A power supply is provided. The power supply includes a power supply circuit and a control circuit. The power supply circuit includes a voltage converter and multiple point-of-load circuits. The voltage converter generates a third voltage according to a first voltage. The load point-of-load circuits generate at least one second voltage and at least one state signal according to the third voltage. The at least one second voltage is suitable for supplying power to a load. The control circuit is coupled to the power supply circuit. The control circuit determines whether a single event latch-up occurs in the power supply circuit according to the at least one state signal. When the single event latch-up occurs in the power supply circuit, the control circuit switches off the power supply circuit to stop generating the at least one second voltage and the at least one state signal.
