Course Objectives

  1. The objective of the course is to design a power converter for a given application

Course Outcomes

Course Outcome:
1. Design the power stage for various converter topologies i.e. both isolated and non-isolated based on specifications
2. Design the magnetics (inductors and transformers) for different converter topologies
3. Derive the averaged switch model of the various converter for circuit simulation
4. Derive the various transfer functions for converter operating in both CCM and DCM
5. Design the controller for voltage and current mode control
