Turn On/Off Time Analysis
This analysis measures the time taken to get to the steady output
voltage of the power supply after the input voltage is applied (turn
on time) and for the output voltage of the power supply to turn off
after the input voltage is removed (turn off time).
Figure 7. The turn-on analysis measures the time taken to get to the
steady output voltage of the power supply after the input voltage is
applied.
Transient Response Analysis
Power supplies are subject to transient conditions, such as turn-
on and turn-off transients, as well as sudden changes in output
load and line input voltage. These conditions lead to one of the
key specifications of the power supplies; load transient response.
This analysis measures the load transient response of the DC
output, namely the time taken for the DC output to stabilize
during a load change.
Figure 8. The transient analysis measures the load transient response
of the DC output, namely the time taken for the DC output to stabilize
during a load change.
Efficiency Analysis
Efficiency analysis tests the overall efficiency of the power
supply by measuring the output power over the input power. This
analysis requires a 4- channel oscilloscope because input voltage,
input current, output voltage, and output current are measured.
