Abstract

The power semiconductor filter (PSF) is used to attenuate conducted electromagnetic interference (EMI) by controlling a series pass device (SPD) operated in linear mode. A fixed-frequency dynamic ramp modulator is adopted to address the input current oscillation issue that may occur in variable-frequency operation and minimize the power dissipation in the SPD. In order to enhance the EMI suppression capability, the fast-current regulation circuit has been optimized to obtain higher loop gain and phase margin. The EMI suppression performance degradation caused by the ground loop inductance has been analyzed; PCB layout guidelines are given to alleviate such adverse effect. A 100W buck-boost LED driver has been built to evaluate the EMI attenuation performance of the PSF.
