Today, semiconductors are increasingly contributing to a more efficient energy ecosystem through energy generation, conversion, distribution, storage and usage. By 2030, it’s expected that 80 percent of energy flow in the U.S. will go through semiconductor devices. The “smart” prefix has long and frequently been used in energy and power management with diverse connotations such as smart grid, smart inverter, etc. The growing “smart” trend is also seen through the omnipresence of semiconductor content in alternative energy. This brief provides an overview of how smart power is paving the way for smart applications.
