9. Performance of Evaluation Board
9.1. Power Factor at Rated Load Condition
Figure 27 shows the system PF performance for the entire input voltage range (90V to
265V) at different input frequency conditions (47Hz, 64Hz). The PF slightly changes
according to the input frequency but can achieve over 86% at 265V
AC
condition.
