Microchip公司的冰箱压缩机参考设计(RCDRD)是采用dsPIC33EP64MC202 微控制器和PMSM马达,比传统的单相AC马达具有较高的效率和更低的噪音.典型冰箱电控系统有两个控制板:一个是冰箱系统控制,另一个是压缩机控制.冰箱压缩机开发参考设计(RCDRD)给工程师提供采用dsPIC®数字信号控制器(DSC)开发PMSM压缩机控制应用的机会,提供有竞争力无传感器控制解决方案,可用于内永磁同步马达(IPMSM)和表面永磁同步电动机(SPMSM)压缩机.两者都提供了硬件和软件解决方案.参考设计的额定输出电流为0.65A(RMS),工作电压187V-264V单相电压,连续输出功率大约为250W,峰值输出功率为350W.中电网为您整理如下详细资料,本文介绍了dsPIC33EP64MC202 微控制器主要特性和框图,以及冰箱压缩机开发板主要电指标,框图和电路图.

PMSM motor is getting widely used in household electric refrigerator compressors for its higher efficiency and lower noise over traditional single-phase AC motor. A typical refrigerator electrical control system has 2 control boards,one is for refrigerator system control, another for compressor control.

This Refrigerator Compressor Development Reference Design (RCDRD) is intended to aid the engineers to develop the PMSM compressor control application with dsPIC® Digital Signal Controllers (DSCs). This development Ref Design is targeted to provide a competitive sensor-less control solution applies to both Interior Permanent Magnet Synchronous Motor (IPMSM) and Surface Permanent Magnet Synchronous Motor (SPMSM) compressor. Both hardware and software are provided.
