Power electronic building block applications in optimization, control, and simulation.

摘要

Power electronic building blocks (PEBB) are modularized power electronic components with local control and with advanced sensing and protection capability. The fundamental block is the basic switch, be it a transistor, SCR, or other device. With the appropriate interfacing, the device can be made to operate from a generic digital signal, removing the need for gate isolation design. Integrated measurement of terminal quantities removes the need for adding sensors for control or protection. These basic blocks can be used to construct complex units such as inverters or rectifiers. By adding additional integrated control and making use of the sensing capability provided by the discrete signals and performing a given function. The top-most level provides coordinated control of the various modules to achieve system-wide objectives.; The power buffer is introduced here as a means to decouple load-source dynamics. Ripple correlation control is analyzed and the present theory expanded upon. The ripple correlation control method is shown to be a virtually ideal optimization method that is truly plug-and-play for a class of systems. The PEBB concept is applied to the hybrid electric vehicle to illustrate that it provides design simplification, enhanced reliability, and a method by which global control objectives can be dynamically altered. Finally, the Power Electronics and Machines Toolboxes are introduced for dynamic simulation of complex systems containing power electronic elements and machines.
