Observer Design for a three-cell chopper using a discrete-time model

Résumé

The multicell converters are very interesting in high voltage power conversion since the switching voltages are reduced considerably and the harmonic spectrum of the output signals are improved. For closed-loop control purposes, measurements of state variables are required but are expensive to obtain directly especially when the cells number increase. In order to avoid the voltage sensors in these converters, a full-order observer using the load current measurement, is presented here. Design of the observer is done for a three-cell chopper and is based on an exact discrete-time model.
