LLC resonant half-bridge converter design guideline

Introduction
The growing popularity of the LLC resonant converter in its half-bridge implementation (see
Figure 1) is due to its high efficiency, low level of EMI emissions, and its ability to achieve
high power density. Such features perfectly fit the power supply demand of many modern
applications such as LCD and PDP TV or 80+ initiative compliant ATX silver box. One of the
major difficulties that engineers are facing with this topology is the
