20140312966 | ACTIVE EMC FILTER - Active EMC filter connectable between an electric power source and an electric load, comprising: capacitors (C×N, C×U) connected between active conductors of said power source and a star point electric node; a filter capacitor (Cst, CstU) connected between said star point and ground; | 10-23-2014 |
20130228424 | ROCKER SWITCH UNIT - A removable rocker switch unit ( | 09-05-2013 |
20130222078 | EMC FILTER CIRCUIT - An EMC filter circuit ( | 08-29-2013 |
20130154766 | FEED THROUGH EMC FILTER - An EMC power filter comprising a filter circuit and a conductive housing ( | 06-20-2013 |
20130141200 | INTEGRATED MAGNETIC DEVICE FOR LOW HARMONICS THREE-PHASE FRONT-END - An integrated magnetic device for low harmonics three-phase front-end ( | 06-06-2013 |
20130121050 | INTEGRATED MAGNETIC DEVICE FOR LOW HARMONICS THREE-PHASE FRONT-END - 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. | 05-16-2013 |
20130121043 | HARMONIC CANCELLING INTERPHASE MAGNETIC DEVICE - A harmonic cancelling interphase magnetic device ( | 05-16-2013 |
20100134204 | HARMONIC FILTER - A Passive harmonic filter (F) has an input node (B) for connection to a power supply ( | 06-03-2010 |
20090121805 | LOW-LEAKAGE EMC FILTER - 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. | 05-14-2009 |
