摘要： A high-frequency amplifier for an active EMI filter with a symmetric class B emitter-follower output stage driven by a driver stage, with a sense output resistor. Both terminals of the sense resistor are brought to the noninverting, respecting inverting input of the driver stage through two dividers of the same ratio, in a global voltage feedback loop. The amplifier is configured to provide a high output impedance at 10 kHz and up to 100 MHz, a peak-to-peak output current of 2-10 ampere and a low quiescent current of less than 400 mA. The invention includes EMI filters with such a high-frequency current source, for example in the current-sense current-inject feedback configuration.

摘要： Electromagnetic interference filter for suppressing interferences in DC network, the network comprising a source device powering a load device via a bus connectable to the source device at an input side and to the load device at an output side.
The EMI filter being connected to the bus and comprising an active filter circuit having an active filter bandwidth and being configured to sense a noise component superimposed in the bus and inject a cancelling noise in the bus to suppress said noise component. The EMI filter further comprises a passive circuit including a source circuit connected to the bus at the input side and a passive load circuit to the bus connected at the output side, the passive circuit being configured to provide, at least at a cutoff frequency of the active filter bandwidth, a source impedance at the input side that differs from a load impedance at the output side by a factor of at least two.-

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.

摘要： An EMC filter circuit (1) has an essentially rigid busbar (3) for carrying an electric power to which is superposed a noise component in a conductive housing (2), which connected to ground. The filter (1) has two main elements inductors (4) increasing an impedance of the bus bar and capacitors (5) connected between the busbar (3) and the conductive housing (2). The capacitors (5) are inserted and tightly held solderless in position between the conductive housing (2) and the electric conductor (3). One advantage comes from the fact, that flat connection elements are arranged on both sides of the capacitors (5), which allow an easy manufacturing process.

摘要： EMC filter, connectable between a supply network and an electric operated appliance to reduce conduction noise between said supply network and said appliance, comprising one voltage regulator having an output terminal whose potential is kept close to the earth potential, in order to reduce the voltage drop, at mains frequency, across a “Y” capacitor or an active shunt module. In this way the leakage current to earth is sensibly reduced. The device of the invention is especially useful in corner-earthed three-phase lines or in conjunction with RCD devices.
