Abstract :
Excitation strategies are explored as part of an overall design to minimize mass and maximize efficiency of a 2 kW portable power generator. The design includes 16 variables and is based upon a magnetic equivalent circuit model that includes core loss. Despite the influence of saturation and core loss, a relatively straightforward field-oriented type control is derived that is consistent with the goals of mass and loss reduction. Design and control are validated through hardware experiment.
