Abstract: A resonant converter and its controlling method are provided. The resonant converter includes a bridge switching circuit receiving a DC input voltage through its power terminal, a resonant and transforming circuit, a rectifying and filtering circuit, and an over-current protecting circuit. The resonant and transforming circuit has at least one resonant capacitor charged/discharged in response to the switching of the bridge switching circuit. The rectifying and filtering circuit rectifies and filters outputs of the resonant and transforming circuit, and generates a driving voltage accordingly. The over-current protecting circuit is coupled to the power terminal and crosses over the resonant capacitor to form a clamp path. The over-current protecting circuit detects a current flowing through the resonant and transforming circuit or a load and determines whether to conduct/cut off the clamp path according to the detection result to limit a cross voltage of the resonant capacitor within a first voltage range.

Abstract: A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load.

Abstract: A power apparatus, a current detecting circuit and a current detecting method are provided. The power apparatus includes a power conversion circuit and the current detecting circuit. The power conversion circuit generates an output current. The current detecting circuit includes first and second current sensing resistors and a control circuit. The first current sensing resistor and the second current sensing resistor sense the output current to generate first and second sensing voltage, respectively. The control circuit receives the first sensing voltage and the second sensing voltage, and converts the first sensing voltage and the second sensing voltage respectively into a first current sensing value and a second current sensing value. The control circuit triggers a protection mechanism when the first current sensing value is greater than a first overcurrent protection value. In the case where the first current sensing value is not greater than the first overcurrent protection value, the control circuit triggers the protection mechanism if the second current sensing value is greater than a second overcurrent protection value. The first overcurrent protection value is greater than the second overcurrent protection value.

Abstract: A power supply apparatus including a master power converter and a slave power converter is provided. The master power converter generates a main power having a working voltage level. The slave power converter generates an auxiliary power. According to its operation state, the master power converter provides a corresponding control signal to the slave power converter. If the master power converter determines the operation state is a first operation state, the slave power converter generates the auxiliary power having a voltage level lower than the working voltage level, so that the slave power converter can be operated in a no-load conversion state. If the master power converter determines the operation state is a second operation state, the slave power converter raises the voltage level of the auxiliary power to the working voltage level, so that the auxiliary power replacing the main power is supplied to a load.
