| Abstract |
Some power electronic simulators use a very simplified switching model: binary representation (Ron, Roff). They give waveforms in the converter and short computer time. The model excludes switching phenomena. In the other simulators, an electrical model of the semiconductor is used; their relative complexity leads to long computer times and difficulties in finding parameters. In this paper we propose a different approach for modelising switching function which satisfies the
requirements of simulator users:
-macroscopic - microscopic information
-limited computer times
-parameters that are easy to find in semiconductor hand book or to work out from circuit designer know-how.
We examine dynamic interactions between switch and networks, show the speed limitation effect (dl/dt, dV/dt) proper to the device and its drive. The principles of modeling the switch function as speed limiter are proposed. A model for bicontrolled switch and diode is presented. The simulation of a static converter is given and demonstrates the utility of this new approach of modeling. |
