The Buck Converter - Principle of Operation, CCM & DCM
This lecture describes the principle of operation of the Buck converter, in both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM), and solves for the steady-state operating point. In the case of DCM, a constant current load, constant voltage load, and constant resistor load are each considered.
The particular application of interest behind this video is the use of a DCM Buck converter as a high efficiency Constant Current Source.
