Choking off EMI/RFI in off-line switchers
by Jim Earley, President, Premier Magnetics Electromagnetic interference (EMI) and radio frequency interference (RFI) are natural byproducts of switching power supplies. Much of this noise arises as a direct result of the large voltage swings caused by short-duration charging and discharging in the power supply circuitry. Common mode noise, which is generated through the power […]
