Abstract: A magnetic core includes an ellipse-shaped central post and two side posts. The ellipse-shaped central post includes a long axis and a short axis. The length of the long axis is greater than the length of the short axis. The two side posts are disposed on two sides of the ellipse-shaped central post and opposite to each other. The two side posts are connected with the ellipse-shaped central post through two connecting portions respectively for defining at least one winding space with the ellipse-shaped central post. By utilizing the ellipse-shaped central post, the volume of the winding space is increased, the diameter of the wire of the winding coil can be increased, the temperature of the winding encapsulation is easy to be lowered, the over-volume issue of the winding encapsulation is avoided, and the safe distance between the bobbin and the winding encapsulation is increased, so that the present disclosure meets the safety regulation.

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 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.
