Smaller, more powerful, better performance...are the buzzwords in the area of DC/DC module power supplies. Good thermal management of the heat generated has become an important part of the design-process. But what needs to be done?
An indisputable fact is that the efficiency of any energy conversion process is always less than 100%. That means that a part of the energy being changed goes astray, in other words, is converted into heat and that ultimately this waste heat must be removed. The laws of thermodynamics state that heat energy can only flow from a warmer to a colder environment.
