The above mentioned list of EMI filters could be designed as widespread-manner filters by bringing in an extra reference conductor. As is effectively-regarded, widespread-manner currents are induced by way of parasitic capacitance to an out of doors reference, such as steel during the chassis or some external conductor (i.
