No matter how efficiently your subsystem delivers energy, the residual dissipation and your ability to remove heat from the system limits power density. Waste energy, in the form of heat, is the enemy of power system designers. Although converter technology continues to increase efficiency, particularly components based upon Vicor’s Sine Amplitude Converter (SAC), there will always be some waste heat that needs to be removed. Power Electronics Europe features an article by Gary Gill, Vicor’s Director V.I Chip Product Line, which defines the problem, explaining that heat is typically the factor that limits power...
