It is also possible to simulate the VAV unit damper stuck closed fault, the availability schedule of the terminal unit was set to zero by an EMS actuator; whereas the VAV unit damper stuck open fault
was simulated by setting the minimum airflow fraction schedule value to one.
If the open fault is not dealt with in time, the voltage stress of certain switch will increase owing to the fluctuation of capacitor neutral-point voltages.
However, for the open fault of half-bridge switches, the DC-link voltage utilization ratio is half of this inverter.

resistances for circuit fault drain of open circuited M1.
A semisupervised learning model is employed for line-line and open fault
detection and classification in PV arrays .
The climate information collected by Winograd's group comes from Devils Hole, an open fault
zone in southwestern Nevada.
Figure 8 shows a comparison between the usage of DBN and BN for diagnosing the window open fault
, which causes increased infiltration.
The 13 suspects included one transistor stuck-on, one transistor stuck-off, five bridges, and six open faults
. That corresponds to a resolution improvement of 350/13 = 27X.
Internal "digital" faults lead to internal stuck-at faults, bridging faults timing faults or open faults
that can appear at any point of a digital signal processing path.
First, the authors target not only catastrophic types of faults (such as stuck-at faults or hard bridging faults), but also parametric types of faults (including both resistive open faults
and resistive bridging faults between interposer wires).
