Abstract:
Power supply designers are now the necessity to increase the power density and have an efficient thermal management. An answer to this is in the resonant topologies that more often use the LLC resonant converter. For these topologies, the MOSFET parasitic capacitances can affect the total behaviors increasing switching losses and decreasing efficiency. Aim of this article is to compare the electrical performances of the two most recent ST MOSFET Superjunction technologies, MDmesh II PlusTM low Qg and MDmesh V technology respectively and compare them to the well-known Super-junction competition devices.
