Can we get Power loss(mainly MOSFET) & efficiency calculation for Buck converter directly using Pspice?

We want to calculate power loss (both switching & conduction) of MOSFET & other devices in Multiphase buck convertor.Also we require to calculate efficiency & provide result directly on tool using Pspice.Can we pspice directly provide both if we enter the correct inputs?

Hi Nitesh,

Please refer to the app note here - https://www.pspice.com/sites/default/files/Single-Switch-Forward-Converter-App-Note_Final.pdf. This should give you an idea of how to calculate both conduction and switching losses and also efficiency of MOSFET's in PSpice

Hi 

Thanks for your support.I gone through the document & I found we can get the losses & efficiency from pspice simulation.

But in this document they have given very small description.Do u know any document which can give detail steps to get it?

Also in this they have given average power loss & switching loss of Mosfet but I also require conduction loss related information.

If u know that please provide me the link or document for detail steps.
