March 24, 2006—International Rectifier, a world leader in power management technology, has introduced a motor control platform for air conditioning applications that enables 95 percent efficiency, quieter operation and mechanical simplicity. IR’s iMOTION integrated power design platform enables energy-saving, variable-speed sinusoidal current control without the need for position sensors for smooth torque output and lower acoustic noise in motors, says the company.
The International Rectifier power design platform is an optimized system architecture that combines IR’s proprietary high voltage integrated circuit (HVIC) technology with analog, digital and power building blocks, along with digital control algorithms, for sensor-less motor control applications using dc link phase current sensing.
Leading manufacturers of computers, energy efficient appliances, lighting, automobiles, satellites, aircraft and defense systems rely on IR’s power management benchmarks to power their next-generation products.
The company’s iMOTION integrated design platform consists of a development system, mixed-signal analog chip sets and power stages, which when co-designed together, simplify motion control designs and bring energy-efficient, cost-effective solutions to market faster. More details on the iMOTION platform, as well as links to design assistance, are posted on the iMOTION Web page. More on the company can be found at its Web site.
