INTELEC is an annual conference which examines and analyzes the latest developments in telecommunications energy systems and related power processing devices and circuits. Technical papers present research and new developments in power electronics and telecommunications power systems, including DC power plants, powering architectures, AC systems, DC-DC converters, batteries, prime power systems, grounding, physical and thermal design, alternative power (engines, fuel cells, etc) and building and equipment cooling systems. There are also tutorials and a technical exhibition of products and equipment. PELS is the sole sponsor of INTELEC when it is held in North America in even-numbered years and provides technical support when the conference is held outside North America.
