Gain characteristics of multi-output LLC resonant converter

摘要

This paper describes the gain characteristics of a multi-output LLC series resonant converter by using the new analytical method. Specially, using the Math-CAD simulated result, this paper analyzes an influence from the secondary leakage inductance of transformer. The theoretical results are verified through an experimental prototype of the 430W 3-output LLC resonant converter for 46 inch PDP power module.
