Abstract: An electronic device includes a casing, a circuit board and a grounding assembly. The circuit board has a first surface and a second surface, wherein an input terminal and an output terminal are disposed on the second surface. The grounding assembly comprises a conducting terminal, a first grounding element and a second grounding element. The conducting terminal is disposed on the first surface of the circuit board, and the first grounding element is disposed adjacent to the conducting terminal. The first grounding element penetrates the circuit board and electrically couples with the conducting terminal and the casing, and the second grounding element correspondingly penetrates the circuit board and the conducting element, so that a first portion of the second grounding element electrically couples with the input terminal and the output terminal of the circuit board, and a second portion of the second grounding element electrically couples with the conducting terminal.

Abstract: An inverter and a control method are disclosed herein. The inverter includes a first switching circuit, a second switching circuit, and a DC-AC converting circuit. The first switching circuit is configured to selectively switch between connecting a first input terminal receiving an AC source and an output terminal of the inverter, and connecting a second input terminal receiving a DC source and the output terminal of the inverter. The second switching circuit is configured such that the first input terminal and the output terminal are connected during the switching process of the first switching circuit. The DC-AC converting circuit is electrically coupled between the second input terminal and the first switching circuit and configured to be operated in a current control mode to convert the DC source to AC power when the first switching circuit is switched to connect the second input terminal and the output terminal.

Abstract: A power supply device is disclosed. A circuit board is disposed inside a conductive housing. A rectifying module is disposed on the circuit board and has primary and secondary sides. The grounding module includes a first grounding element, a second grounding element, and a fastening element. Two terminals of the first surge protection module are respectively electrically connected to the primary side and the first grounding element. Two terminals of the second surge protection module are respectively electrically connected to the secondary side and the second grounding element. The second grounding element and the first grounding element are not directly connected. The fastening element passes through the conductive housing, the circuit board, the first grounding element, and the second grounding element so that the conductive housing, the first grounding element, and the second grounding element are electrically connected to one another.

Abstract: A transmission and distribution system with electric shock protection function includes a transmitting terminal and a receiving terminal. The transmitting terminal includes a switch, a current measurer, a signal generator, and a controller. The receiving terminal includes a filter. The switch is coupled to a first DC power and a transmission line. The current measurer is coupled to the transmission line, and measures a current of the transmission line and provides a current signal. The signal generator provides a disturbance signal to the transmission line. The controller receives the current signal and controls the switch. If the controller determines that the current signal contains the disturbance signal, the controller turns off the switch.
