Power modules for variable-speed motor control

摘要

Demand is growing for appliances such as washing machines, refrigerators, and air conditioners to help improve domestic energy efficiency. Moving from conventional fixed-speed motors to variable-speed operation could save as much as 30% of energy consumed, but appliance vendors must deliver this increased efficiency at little or no extra cost to end users. Several solutions have emerged to ease the digital design of such a project, but designers also need integrated modules and associated design tools to facilitate design of the power stage.
