摘要： Coil formers having flanges selectedly removed at interface areas with a core can provide advantages of increase a winding window and better heat transfer. The coil former can also have added flanged adjacent to the core to provide added protection to the core. Examples of e-cores and PQ cores are shown.

摘要： The present patent application describes a charger for electric vehicles that features a fault ride through capability, allowing it to use power from the vehicle's battery as a backup power source during low voltage faults of the grid. The charger includes a backup circuit that comprises a first coupling circuit connected to the power path of the electric vehicle battery through the charger, a second coupling circuit connected to the power path of the charger's power supply, and optionally a connection or conditioning circuit to match the voltages of the coupling circuits. The backup circuit enables the control and communication units of the charger to keep operating during low voltage faults of the grid, which can vary in duration from milliseconds to several seconds. The coupling circuits may be placed at various points in the charger's circuitry, such as the input, output, or internal points of the converter or power supply.
