Industry 4.0, the current trend of automation and data exchange in manufacturing technologies, continues unabated, fueling the vision of the “smart factory.” The smartfactory relies on electronic equipment to collect, synthesize, and act upon data.The new technologies and approaches to manufacturing, also dubbed the Industrial Internet of Things (IIoT), have the potential to improve efficiencies and, by extension, profitability. The adoption of IIoT technologies introduces issues in energy efficiency, solution size, system safety, and reliability. This design guide reviews the megatrends underlying the Industry 4.0 revolution and their associated challenges. It then examines new solutions for power management using several case studies.
