A highly regarded topology…
The LLC topology is widely recognized as the most beneficial for switching converters in the 80…1000W power range and it’s increasingly used in applications up to a few dozen kilowatts, such as electric vehicle charging equipment, for the benefits it offers when it comes to EMC, efficiency, dimensions of the magnetic components of the resonant tank and the filters.
Since the cost of the magnetic components is in broad terms proportional to their dimensions, a cost advantage follows.
