Abstract: A charging circuit interrupting device for applying an input voltage provided by first and second input power lines of a power system to first and second output power lines of an output system includes a current-detecting unit, a self-test device, and a controller. The current-detecting unit executes a leakage-detection function and generates a leakage signal when the current difference between the first and second power lines is detected. The self-test device generates a bypass path according to the detection enable signal so that there is a current difference between the first and the second input power lines. When operating in a self-test mode, the controller generates the detection enable signal, determines that the leakage-detecting function is normal, and enters a normal mode to apply the input voltage to the output system when the leakage signal is received.

Abstract: A charging device for charging an electric vehicle includes a power plug, a charging gun, a control box, a temperature detecting circuit and an over-temperature protection circuit. The charging gun is detachably connected with the electric vehicle and includes a connection confirmation terminal and a connection confirmation circuit. The connection confirmation circuit outputs a connection confirmation signal to the connection confirmation terminal. The temperature detecting circuit detects the temperature of the power plug or the control box and outputs a temperature signal to a second control unit of the control box when the temperature of the power plug or the control box exceeds a threshold temperature level. The over-temperature protection circuit is electrically connected between the second control unit and the connection confirmation terminal. The second control unit controls the over-temperature protection circuit to adjust the voltage level of the connection confirmation terminal according to the temperature signal.

Abstract: A ground-resistance detection device, which is coupled to a power system including a first power line, a second power line, and a protective earth, includes a ground-resistance detection circuit and a controller. The ground-resistance detection circuit includes a first input node and a second input node. The first input node is coupled to either the first power line or the second power line. The second input node is coupled to a ground terminal. The ground-resistance detection circuit generates a DC output voltage according to the voltage of the first input node, the voltage of the second input node, and the DC reference voltage. The controller determines the ground resistance between the protective earth and the ground terminal according to the DC reference voltage and the DC output voltage.

Abstract: A power system with a power apparatus for an X-ray tube is disclosed. The power system includes an X-ray tube and a power apparatus for the X-ray tube. The X-ray tube has a cathode and an anode. The power apparatus includes a first power conversion unit, a second power conversion unit, and a power switch unit. The first power conversion unit produces a positive voltage and a driving voltage and the second conversion unit produces a negative. When the power switch unit is turned off by the driving voltage, the power apparatus outputs the negative voltage to suppress electron flow energy generated from the cathode of the X-ray tube, whereas the power apparatus outputs the positive voltage to provide electron flow energy to the anode of the X-ray tube when the power switch unit is turned on by the driving voltage, thus producing X-ray.
