介绍了一种基于可编程片上系统(PSOC)的宽量程电能计量模块(EPSOC)的结构与原理,分析了自调增益算法及同步采样算法。通过EPSOC的实现,利用PSOC特有的自调量程技术,能使电压量程宽达46～460 V,电流量程宽达0.5～120 A。EPSOC可以测量电压有效值、电流有效值、有功功率、无功功率等电力参数,可以用于单(三)相电能表、电量变送器,也可以用于电力监测装置。

Structure and theory of wide magnitude electrical energy measurement module based on PSOC (EPSOC) are introduced in this paper,adjustable range algorithm and synchronous sampling are analyzed. Its voltage magnitude can be from 46 V to 460 V. Its current magnitude can be from 0.5 A to 120 A,by realization of wide magnitude electrical energy measurement module and adjustable magnitude technology. Some electric paramentrs such as voltage rms value,current rms value,active power and reactive power can be measured. EPSOC can be used for single (three) phase electrical energy meter,electrical quantity transducer,and power monitoring equipment.
