Power supplies are the major life-limiting component in most electronic systems. Ridgetop Group’s RingDown™ uses a patent-pending technology to create an advanced prognostics-enabler, the key to providing the higher reliability and improved serviceability needed in mission-critical systems and devices. Far superior to the current static load testing method, RingDown is a non-invasive health monitoring system that requires no modification to the power supply circuit.

Power supplies employ closed-loop feedback to keep the voltage or current under tight control and regulation. While the power system may still be in regulation, certain aging- or stress-related changes to internal components can indicate impending failure conditions on the supply.

By externally monitoring transient responses to source or load changes, RingDown accurately predicts wear-out by analyzing transient response to determine state of health (SoH) and remaining useful life (RUL) metrics. The transients on the power supply “rails” produce the characteristic “ringing” waveform, which reveals the characteristics, or eigenvalues, indicative of system health. Departures from the standard response can be directly mapped to equipment degradation or devices approaching the end of their useful operational life, and provide the basis for a unique and non-intrusive prognostic for the power supply under test.

One of RingDown’s best functions is superb sensitivity and precision – imagine the advantages of detecting failure signatures before performance is noticeably reduced.
