Abstract	A strategy of non-linear control, the objective of which is to maximize the power output Pilec of a one phase Transverse-Flux Permanent Magnet (TFPM) machine with flux concentration, using a forced commutated rectifier in a wind turbine application is investigated. In a TFPM machine, the per unit stator reactance Xs is raised and the saturation in the stator magnetic core develops non-linear behaviour which the control strategy has to take into account. The focus will be put on the development of a relation between the average torque T and the stator current I., determined by means of a TFPM machine modelling tool, based on finite element method. The trajectory for the maximum torque-to-current ratio is derived and used as a control law to maximize the TFPM machine power output Pélec. Power increases of about 10% are established when we apply this control law with the optimized value of phase angle y , compared to a control law which imposes a zero phase angle y/. Control system simulations including the TFPM machine model with a power rectifier and experimental test are also used to validate results.
