Appliances today must meet global compliance requirements for Electromagnetic Compatibility (EMC), and meeting regulatory compliance is complicated by the ever increasing use and density of electronic components. Within a larger appliance are various circuit components and modules that are generators of electromagnetic interference (EMI), and those that are highly susceptible to EMI noise. Each circuit portion must be individually filtered to suppress EMI, or the appliance product as a whole could fail EMC compliance. (See Fig. 1.)
