    摘要： A safety device for an automotive EMI filter that is connected in series with a filtering capacitor. The safety device has normally a low impedance and does not alter the functioning of the filter, but it is configured to present an increased inductance in the event of a discharge. The device reduces the discharge current that can be accidentally conducted through a human body.

    摘要： A harmonic cancelling interphase magnetic device (1) comprising a magnetic core of rectangular shape with three wound legs (14) and two non-wound legs (12), wherein the cross-section of said non-wound legs (12) is thinner than the cross-section of said wound legs (14). The magnetic device is designed for a front end multi-pulse rectifier or inverter. Its use enables reduction of the harmonics of the currents absorbed or injected to three-phase power line. Compare to known solutions, cost, material and dimensions of the magnetic device are significantly reduced.

    摘要： Active EMC filter connectable between an electric power source and an electric load. The filter has capacitors (C×N, C×U) connected between active conductors of the power source and a star point electric node. A filter capacitor (Cst, CstU) is connected between the star point and ground. A half-bridge has two switching devices (T3, T4; T1, T2) connected in cascade between a positive supply voltage and a negative supply voltage. A smoothing circuit (RgN, LgN; RgU, RgU) is connected between a common node of the switching devices and the star point. A control unit (Drive_N, Drive_U) drives the switching devices (T3, T4; T1, T2) digitally either in an ON-state or in an OFF-state, such as to limit a leakage current.

    摘要： An integrated magnetic for a low harmonics three-phase bidirectional front-end and also for AC/DC and DC/AC power converters. Its use enables reduction of the harmonics of the currents absorbed or injected to three-phase power line by using only one device which integrates a splitter and an inductor function. Compared to known solutions, cost, material and dimensions of the integrated magnetic device are reduced thanks to the magnetic core comprising three closed sub-assemblies and one or more jokes, separated by air-gaps from the sub-assemblies.
