High Performance iMOTION™ Platform Enables 95 Percent Efficiency in Air Conditioning Applications
International Rectifier, IR® (NYSE: IRF), 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.
IR’s iMOTION platform is one of the first of its kind to address energy-saving Motor Control from a systems level
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.
The air conditioning platform features a proprietary algorithm for interior permanent magnet synchronous motors (IPMSM) in the compressor as well as the fan, and includes power factor correction (PFC). This, combined with IR’s application-specific HVICs and discrete trench IGBTs, achieves 95 percent converter efficiency.
