This chapter introduces the fundamentals of dynamic characterization. Starting from the switching commutation analysis in an actual power electronics converter, the simplified test circuit for dynamic characterization is derived such that not the whole converter will be needed for the test. Then, fundamentals of DPT based on the simplified test circuit are introduced, including operation principle, configuration, and setup. Detailed DPT design and control are discussed. In the end, according to the design theory, a case study is given. Two-level voltage source converter is the focused topology in the following description, since it is the one of the most widely used converter types.
