Abstract: 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.

Abstract: 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.
