ABSTRACT:
A power supply in accordance with the present invention includes a chassis (26) associated with the power supply; a voltage source (12) providing an output voltage varying at a fundamental frequency and having a noise component changing as a function of time at a frequency above the fundamental frequency; a filter (41) including an inductance (44) in series with the voltage source for attenuating the noise component and outputting the fundamental frequency; and a cooling apparatus (42) thermally and capacitively coupled to the inductor for conducting heat from the inductor and shunting the noise component to the chassis.
