In order to get good insight into how to improve the power efficiency of any electronic system, determining the power factor is crucial. The lower it is, the more efficient the system is. Aside from that, all relevant power components from the power triangle need to be calculated. This means that power monitoring chips like the ACS37800 are able to provide the real power, also called the active power, as well as the imaginary power, also called reactive power. It is also the combination of both, with the apparent power. This is all possible because the IC not only provides the instantaneous voltage and current, but also the Root Mean Square (RMS) calculated value on a full cycle, as it is required in the apparent power equation. To get even better accuracy, having the power monitoring IC to average every 1 second to 1 minute of the current, voltage and active power is necessary, and saves CPU cycles from the computational component of the system. All of these parameters can be discretely calculated, but a single IC could simplify the design process and shortening the time to market for any energy-conscious application.
