摘要： A driving circuit for driving a power switch. The driving circuit and the power switch are collaboratively defined as an equivalent circuit. The equivalent circuit includes a first equivalent capacitor corresponding to an input capacitor of the power switch, an equivalent inductor, and a second equivalent capacitor corresponding to a parasitic parameter of at least one driving switch. In the charging procedure or the discharging of the first equivalent capacitor, a change amount of charges in the first equivalent capacitor while a voltage of the input capacitor is changed from a voltage corresponding to no inductor current to a set voltage is larger than or equal to a change amount of charges in the second equivalent capacitor while the voltage of the input capacitor is changed from the voltage corresponding to no inductor current to a steady voltage.

摘要： A power module includes a circuit board and a load group. The load group is installed on the circuit board. The load group includes a first-stage power conversion circuit, a second-stage power conversion circuit and plural loads. The first-stage power conversion circuit converts an input voltage into a transition voltage. The second-stage power conversion circuit converts the transition voltage into a driving voltage. A rated value of the first input voltage is higher than twice a rated value of the transition voltage. A rated value of the driving voltage is lower than a half of the rated value of the transition voltage. The distance between the input terminal of the second-stage power conversion circuit and the output terminal of the first-stage power conversion circuit is smaller than the distance between the input terminal of the first-stage power conversion circuit and each edge of the circuit board.

摘要： The present disclosure generally relates to a test method and system thereof. The test method comprises: outputting a test control signal to a test power supply of the circuit under test so as to adjust an input signal of the circuit under test so that a gain range of the circuit under test in an abnormal operating state is the same as that of the circuit under test in a normal operating state when the circuit under test enters into the abnormal operating state. The present disclosure may meet requirements for equipment test without sacrificing the efficiency of circuits in normal operating state or adding complexity circuit.

摘要： A power converter device, includes switching devices and a controller, to realize conversion between power supplies by controlling on and off the switching devices via the controller. The switching devices include: at least one normally-on type switching device and at least one normally-off type switching device both having an operation frequency greater than 1 kHz and connected in series. The controller outputs a first and second control signal to correspondingly control the normally-on type switching device and the normally-off type switching device to control the normally-off type switching device to be turned on after the normally-on type switching device to be turned off. The present disclosure uses the normally-off type switching device originally disposed in the circuit, having a voltage blocking ability, to realize directly usage of the normally-on type switching device to improve efficiency and power density of switching power supply.
