Figure 7: Output Voltage Ripple
Device Currents
Figure 8 shows the current through various power devices. Observe the current through various devices.
The result can also be used to co-relate this simulation result with simulation result for ideal devices
(Figure 4) to see the effect of actual devices models and change in various output. This analysis is useful
to select devices with appropriate parameters, for example if MOSFET peak current has gone up
significantly, you might see the reverse recovery time of diode used in secondary side and might decide
to go for a device with lower stored charge or faster recovery time.
