Boosting efficiency in resonant converters by the use of a new advanced power MOSFET technology

This work discusses the advantages of a new trench power MOSFET technology applying a new design approach. Along with the improvements recorded in the main switching figures of merit, the recently introduced technology is also proven to shine in soft-switching ZVS applications. It is shown how the new device design practically eliminates one of the loss mechanisms in the device itself when operated in ZVS, supporting a clear improvement in the overall system efficiency.
