Editorial Special Issue on Green Power Supplies

A traditional field for power Electronics, Power supply technology is still the key application area that covers computing, telecommunication, server, data center, industry, automobile, electric vehicles (EVs), medical, appliance, solar inverters, and so on. Recent advances have made power supplies greener than before, as they become more energy efficient, cost effective, and environment friendly. Recent development in silicon power device and in wide bandgap devices has improved power density and conversion efficiency. These emerging devices, together with improvements in topologies, cooling, and passive components, are shrinking the size. Magnetic material, passive component design, and integration have contributed to miniaturization with improved manufacturability. Digital control, with low-cost DSP and other control ICs, has advanced the overall performance significantly.
