EMC requirements for scientific satellites are usually very stringent and much more demanding than terrestrial standards, mainly because ad-hoc scientific instruments developed for the mission require very quiet electromagnetic environments to perform their science. These requirements will assure the compatibility of all instruments on board and with the platform. The electromagnetic noise generated by the DC/DC converter of the PHI instrument, to be flown on board Solar Orbiter, has been drastically reduced applying several different techniques. One technique has been to change the grounding strategy from a single point grounding to a distributed grounding. Two additional techniques were needed to reach the required noise floor. Experimental measurements show the improvements achieved with each technique.
