Set Up and Operation
The user should note that the over current trip levels are set above the peak of the
rated output. This is to allow modest amounts of acceleration/deceleration and to
prevent nuisance trips. The user should avoid operating the system beyond the peak
output of 3.5A continuously. Operation of the system just beneath the over-current trip
levels at the worst case stall condition discussed above, may affect long-term
reliability of the switches and should be avoided. See Figure 1-5.

Input Current Limits Using The Active PFC
The active PFC circuit is capable of 5A RMS input (7.1A Peak) at any AC input
voltage within the entire permitted operating range (voltage, temperature and 50 kHz
modulation frequency).
Thus, the input power and neglecting losses the output power, when using the PFC is
linearly proportional to the input voltage. A commercial application will often maintain
constant output power over the universal input voltage range of 88-265 VAC. This
constant power characteristic was not designed into the system in order to limit the
size and cost of the PFC inductor and switches.
For a fixed RMS input current of the correct half-sinusoidal shape and fixed
modulation frequency, the user should note the following comments as to how
different parts of the PFC circuit are thermally loaded:
PFC inductor thermal loading is relatively insensitive to variations in AC input
voltage or regulated DC bus output voltage.
PFC switches are more heavily thermally loaded the larger the difference between
the AC input voltage and the DC bus voltage (i.e., the larger the average boost
ratio). This is because the average switch duty cycle increases the larger the
boost ratio and therefore the switch conduction loss increases. Furthermore, the
switching loss also increases slightly with boost ratio.

Note:
This is only true provided the correct half-sinusoidal input current
waveshape is being followed and the DC bus is being correctly regulated to
be above the peak of the AC supply.
