Abstract
A system and method for power supply ripple detection is disclosed. A voltage across one or more capacitors of the power supply is measured. An AC ripple voltage component of the capacitor voltage is then filtered and rectified into a DC signal. A level of ripple represented by the DC signal is then compared to threshold values to assess a health of the power supply. In one implementation, the power supplies provide power to control panels of one or more building management systems. The power supplies determine and report information concerning health of the power supplies to the control panels, the information including the DC signal itself and the result of the comparison of the DC signal to the threshold values. A cloud-based connected services system then receives and analyzes the information concerning health of the power supplies forwarded from control panels of multiple building management systems to determine trends.
