Modeling Switching Losses and Efficiency


Thu, September 14th, 2017 from 1:00 - 2:00 PM EDT

This one hour webinar will explore measuring switching losses and efficiency on SIMPLIS circuits. In order to effectively model switching losses, the MOSFET driver circuit must be modeled with more detail than is typical. The driver sourcing and sinking current limits, as well as the saturation resistances, must be realistically modeled for the switching losses to approximate a real circuit. 

Once the driver is accurately modeled, the MOSFETs must be considered, and the non-linear capacitance characteristics understood. Once the combination of an accurate MOSFET model and the driver for the MOSFET is complete, an accurate simulation of the switching losses and the power supply efficiency can be made.
