Implementation of a Three-Phase Electronic Watt-Hour Meter Using the MSP430F677x(A)中计算功率部分代码能否详解下,结合代码。目前看到模拟量采样部分都没有问题,但是功率计算没有看懂。

后台处理AD时用了 sqac_voltage,但是定义中为aqac48_16,而我在工程中搜索不到aqac48_16有用的信息,这几个怎么用的?
#if defined(VRMS_SUPPORT) || defined(POWER_FACTOR_SUPPORT)
sqac_voltage(phase->metrology.dot_prod.V_sq, V_sample);
#endif
#define sqac_voltage sqac48_16
#define sqac_current sqac64_24
#define mac_power mac64_16_24
#define mac_voltage mac48_16
