Input-State Feedback Linearization Control of Two-Stage Matrix Converters Interfaced With High-Speed Microturbine Generators
2007
In this paper the indirect two-stage matrix converter is used with the aim to convert a high frequency output voltage of a microturbine generator to a low-frequency voltage for utility use. Moreover, in order to allow a unity input power factor operation of the electrical generator, an input-state feedback linearization control-law is implemented to control the current flowing between the generator and the matrix converter's input side. Numerical simulations are carried out using matlab and similink software emphasize the two-stage matrix converter's capability in providing sinusoidal output voltage with low distortion. Moreover, the unity power factor operation of the generator is also verified over a wide variation of the active power.
