Simulation of Power Electronic Circuits
نویسنده
چکیده
Power electronic circuits are characteristically variable structure systems with extreme stiffness due to their switching behaviour. Depending on the point of interest, different models and time scales are used for simulation, but in any case, exact consideration of the switching instants is required. At switching instants, the derivatives of switched signals are not continuous, which must be considered when choosing the integration algorithm and when establishing the pulse width. Last not least, spontaneous switching can be caused by diodes when their currents hit zero. In that case, even the order of the differential equation system changes.

A Minimal-Cost Inherent-Feedback Approach for Low-Power MRF-Based Logic Gates
The Markov random field (MRF) theory has been accepted as a highly effective framework for designing noise-tolerant nanometer digital VLSI circuits. In MRF-based design, proper feedback lines are used to control noise and keep the circuits in their valid states. However, this methodology has encountered two major problems that have limited the application of highly noise immune MRF-based circui...
