Description
Calculate energy loss
[(Ilimit) 2 – (Iout) 2 ] * t exceeds
limit value I 2 tmax
Output current exceeds
level set for a
specific time.
Transformer current
exceeds level set (level
is temperaturedependent)
Hardware current monitoring.
Short-circuit
detection with direct
shutdown of the power
stage
As for 21) shutdown
level has been reduced
due to high temperature
(from 110% to
100% of maximum
device current)
Current exceeds permitted
limit
Safe Operating Area
limit (SOA) exceeded,
excessively high transients
have occurred
Possible reason
Measure to rectify
Current above Ilimit for a time
Reduce load
Adjust Ilimit or I2tmax to the load
Controller overshooting on set value steps
Reduce set value ramp
Reduce control parameters
Controller oscillation
Reduce control parameters
10
Hard switching of a low resistance load results in current
spikes from the output capacitors
Reduce brief voltage drop by connecting external
capacitor/series indicator
After consultation with the manufacturer, it may be
possible to increase the delay
Controller overshooting on set value steps
Reduce gradient on the set value ramp
Reduce control parameters
Hard switching of a low resistance load (faster and
larger voltage drop)
Reduce brief voltage drop by connecting external
capacitor/series indicator
Reduce control parameters
Hardware fault
Rectification by manufacturer
See above “22) Overcurrent Iprim”
See above “21) Overcurrent Isek”
Reduce load
Controller is unstable
Reduce gain
Reduce drop voltage
