Effect of Transformer Leakage Inductance on Capacitive Input Filters.

摘要

The effect of series inductance on the performance of the capacitive input power filter has been analyzed by computer and is presented in a set of design curves. The results show that the normally encountered leakage inductance of a transformer has a pronounced effect on reducing the peak and RMS currents in the capacitive input filter circuit. This reduction shows the capacitive input filter to be much more practical than previously believed, especially for high power applications.
