    摘要： A resonance frequency adjusting circuit in electronic communication with a power supply and a load connected to the power supply includes a first LC filter, a capacitor, a switch, and a frequency detecting and control module. The first LC filter circuit is electrically connected between the power supply and the load. The switch is electrically connected between the capacitor and ground. The frequency detecting and control module detects a current transient frequency of the load, compares the current transient frequency with a first resonance frequency of the first LC filter circuit, and controls the switch to turn on/off according to the comparison.

    摘要： A power supply system includes a power supply unit, a number of electrical loads and a sequence circuit. The power supply unit provides power for the electrical loads through the sequence circuit. When any one of the electrical loads fails the sequence circuit will record the failure, shut down and lock the power supply unit to prevent the power supply unit from powering the electrical loads.

    摘要： An active clamping circuit. The active clamping circuit is applicable to a DC-to-DC conversion circuit, and has an output terminal to supply an output voltage to a load. In the active clamping circuit, a determining circuit is coupled to the DC-to-DC conversion circuit to determine the output detects the output voltage and to output a first enable signal when the output voltage is higher than a first predetermined voltage. A voltage adjustment circuit is coupled to the determining circuit to pull low the output voltage according to the first enable signal. An inductor has a first end coupled to the output terminal of the DC-to-DC conversion circuit, and a diode is coupled between the inductor and an input terminal of the DC-to-DC conversion circuit as a conductive path to channel discharge current to the input terminal of the DC-to-DC conversion circuit.
