Modelling, simulation and validation of a twelve-pulse autotransformer rectifier for aerospace applications

Cross, A.M., Forsyth, A.J. and Cooper, B. (2004). Modelling, simulation and validation of a twelve-pulse autotransformer rectifier for aerospace applications. IN: UNSPECIFIED IEE conference publication series, 2 . IET.


A microcap SPICE circuit-level model of a 12-pulse autotransformer based rectifier for an aircraft fuel-pump motor drive is described. The importance of including the nonlinear magnetising inductance of the interphase transformers is illustrated. Small supply voltage distortions are seen to result in current imbalance in the interphase transformers, degrading the rectifier input current, and may lead to infringement of the power quality specification. The model has been validated for various operating supply voltages, frequencies and output powers, against measurements from a 3.75 kW unit.
