Figure 37
Load step :100%→0% at V
Figure 37 illustrates the response of the voltage control loop during a load step from 100% to 0% with a voltage
overshoot up to 425 V. A similar response can be observed at V

Thermal measurements
The board shown in this document (EVAL-PFC5KIKWWR5SYS) is provided with an enclosure. The implemented
thermal concept uses two low-power fans attached to two heatsinks, in which the power semiconductors
dissipate their generated losses.
