Study of the energy flow characteristics in power electronic conversion systems

The way to cost reduction and improved reliability in power electronic converters passes through their modularization and standardization. After the system is partitioned into modules, the characteristics of the interfaces acquire major importance because they provide the information necessary for module interconnection. This paper contributes to the description of the energetic characteristics of the interfaces in a modular system. In order to achieve the goal the energy flow in a power electronic converter is analyzed using proper analytic tools. The analysis is also useful to gain insight on how a power converter processes the energy and eventually find ways for modularization and an improved design.
