| Abstract |
Highly ef_cient and dense power electronic converters are an essential part of aircraft electrical systems. The Swiss recti_er provides an ef_cient application of AC-DC conversion. However, currently used conventional control strategies, such as carrier-based PWM control, have not been able to produce AC currents that meet aircraft power quality standards for the Swiss recti_er. Model predictive control is a control strategy that has recently become popular with the availability of powerful microprocessors and has the potential to improve power quality issues currently faced by the Swiss recti_er in aircraft applications. Therefore, _nite control set model predictive control is used here speci_cally for current control of DC-switches in the Swiss recti_er. This paper consists a design and optimization of a simulation model. The goal is to model the Swiss recti_er to operate with model predictive control and to limit input AC current's total harmonic distortion to less than 5 \% which would suf_ce for aircraft applications as per military standards. The developed phase-based model predictive controller is simulated with different cost functions and the resulting input current THD and switching frequency are evaluated and compared. |
