In view of the global energy crisis, the current focus of electronic equipment is to achieve high power combined with lower energy consumption.
Consequently, many electronics companies are increasing their standards for the efficiency of numerous products in their specifications. These can scarcely be met using conventional hard-switch converters. Developers of power supply units have therefore turned to soft-switch topologies such as the LLC resonant converter in order to improve the efficiency and enable operation at a higher frequency. However, there are a couple of aspects that must be considered.
