APEC: Y-capacitance multiplier IC shrinks EMC inductors

At APEC in Florida, Texas Instruments introduced a family of ICs designed to shrink the size of EMC anti-emission common-mode filters in single and three-phase mains and automotive power converters. In principal, the ICs implement a capacitance multiplier circuit to emulate the Y-capacitors in a conventional passive filter design. They do while sitting amongst smaller ...
