For determining the dynamic on-resistance of a power transistor, the voltage and current waveforms have to be measured during the switching operation. The novel heterostructure wide-bandgap (eg. AlGaN/GaN) transistors inherently suffer from the curre

The effective efficiency of a photovoltaic system is strongly affected by varying factors such as partial shading. The centralized power conversion has limitations to mitigate that problem. As a possible solution the benefits of the distributed power

To adjust the light spectrum of a flash lamp, the current flowing through the flash lamp has to be controlled. An optimal design of a switched resistor bank circuit following a predefined current profile is presented. The optimal values of the switch

For determining the dynamic on-resistance R dyn,on of a power transistor, the voltage and current waveforms have to be measured during the switching operation. In measurements of voltage waveforms, using an oscilloscope, the characteristics of an amp

Publikováno v: Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010.

Observability analysis is a very important tool in state estimation. For a given set of measurements and their geographical location in the system, it determines whether the state of the whole system can be estimated. In this paper a numerical observ
