Abstract: A power module, includes a leadless frame substrate including a first metal layer and an insulating layer, wherein the first metal layer forms a circuit trace disposed on the insulating layer and the first metal layer has an extension structure extending out of the insulating layer to serve as an output terminal; at least one semiconductor power device disposed on the first metal layer; a current detector disposed on the output terminal; and a molding compound, completely covering the first metal layer on the insulating layer of the leadless frame substrate and the at least one semiconductor power device, and partially covering the output terminal so that the current detector is completely disposed outside the molding compound.

Abstract: A power module device, comprising a main switch and a detection unit. The main switch is electrically connected between a first detection node and a second detection node. The first detection node and the second detection node are electrically connected between a plurality of power supply nodes, and are substantially two ends of the main switch. When the main switch is turned on, the main switch is configured to transmit a current flowing through the plurality of power supply nodes. The detection unit is electrically connected to the first detection node and the second detection node, and configured to detect a voltage across the two ends of the main switch to generate a detection voltage.

Abstract: A power processing apparatus includes an input port, an output port, a power transforming module, and a power releasing module. The power transforming module is between the input port and the output port to transform power into predetermined voltage or current. The power transforming module has a capacitor unit connected to LEDs in parallel. The power releasing module has a switch unit to disconnect the resistor unit and the capacitor unit when the power transforming module receives the power, and to connect the resistor unit to the capacitor unit when the power transforming module does not receive the power. Therefore, it may release the residual power to make the LED off in a short time when one turns off the power.
