Application of XC164 in the active motor power detection

This paper introduces application of XC164 which is a 16 bit microcontroller produced by Infineon company in the detection of active motor power. To get the active power, the current, voltage and power factor should be measured. In the system design, the input voltage and current are measured by the method called Synchronous sampling with the A/D Converter. And power factor can be obtained by collecting the phase difference of voltage and current with the Multi-Functional General Purpose Timer Unit of XC164. This system makes full use of the strong DSP performance of XC164 with high precision, high speed of real-time processing and cost-effective features. Taking advantage of the excellent control performance of XC164, this system can also expand its function, such as motor torque detection, energy saving control etc. So it has a great application prospect.
