Abstract
A switching mode power supply generating reduced high frequency noise. The power supply includes a solid state switch, a modulator for driving the solid state switch with a periodic pulse drive signal, an output filter at the output of the solid state switch, where the output filter includes an inductor and a catch diode. A damping element is included for damping current spikes through the catch diode when said solid state switch turns on and thus reduce noise pulses that would otherwise be introduced by the current spikes.
