PCS2_a129 — Loss Of Zcd Event Control

Full alert identifier: PCS2_a129_lossOfZcdEventControl

Alert description

The Power Conversion System (PCS2) has detected that one of its DCDC stage's resonant tank current zero-crossing event measured timing is continuously out of our control

Potential impact

The impacted DCDC stage may have a hardware integrity issue and may not be able to deliver power to its output

Set condition

The Power Conversion System (PCS2) has detected the resonant tank's zero-crossing behavior is out of its control, resulting in zero-crossing event measured timing being irrational

Clear condition

The Power Conversion System (PCS2) no longer detects the irrational resonant tank current zero-crossing event measurement on that DCDC stage
