Efficient Motor/Controls Save Terawatt-Hours/Year Various types of motors now have sophisticated controls to drive them to their maximum potential By Joe Roy Fairchild Semiconductor / South Portland, ME http://www.fairchildsemi.com Contents Viewpoint Gate Drive Schemes for Motor Control Applications Considerations When Selecting the Proper MOSFET Driver Power Modules for Variable-Speed Motor Control Analog news D esigners of appliances and control systems are simultaneously challenged with numerous inflexible targets. On top of that, they need to meet these demands in an environmentally friendly manner consistent with multiple energy policies. In the U.S., energy policies are driven by the Department of Energy (DOE), the Environmental Protection Agency (EPA), and the state of California—which, as the twelfth largest consumer of electricity in the world, has spent decades poising itself as the U.S. leader in energy efficiency. The California Energy Commission (CEC) strives to produce cutting-edge legislation that pushes for advanced technologies with energy savings and lower emissions. Their forward-thinking policies are commonly a template for national U.S. policy. Although these policies and constraints often appear as barriers to the design and release of products, they are also necessary catalysts that promote the innovation that will help keep our planet healthy and energy available. Governments constantly struggle with ways to reduce greenhouse gas emissions, decrease the need for more powergeneration facilities, and keep electrical power affordable. The most cost-effective and timely way to achieve these goals is to require that With the advent of new motor technologies, engineers have many new colors in their pallet—and yes, they are all shades of green.
