摘要： An AC charging system for electric vehicles, which cooperates with a power grid, includes a power detecting module, a local power supplying module, and a local charging control module. The power detecting module is coupled with a second area power converting device of the power grid to generate power parameters. The local power supplying module is coupled to the power output side of the second area power converting device of the power grid for outputting a controllable power source to the electric vehicle. The local charging control module is coupled to the power detecting module and the local power supplying module, and controls each controllable power source provided by the local power supplying module according to power parameters. Accordingly, when a large number of electric vehicles use AC charging at the same time, it can avoid the power supply of the grid being affected by the overload of electricity.

摘要： A fault detection circuit connects to and determines the occurrence of failure in an inverter circuit. The inverter circuit comprises three outputs to connect three groups of lamps respectively, and the fault detection circuit comprises a magnetic unit and a signal detection unit. The magnetic unit comprises first, second and third flux generating windings electrically connected to the three outputs of the inverter circuit, and a flux detection winding. If no fault occurs on the outputs of the inverter circuit, total flux generated by the flux generating windings is cancelled out. As long as any fault occurs on the outputs of the inverter circuit, flux generated by the flux generating windings cannot be canceled out, and the flux detection winding is electromagnetically coupled accordingly and driven by the generated flux to output a coupling signal, based on which the signal detection unit generates an alert signal accordingly.
