The Highest Efficiency Control of the Stirling Linear Generator

Abstract:

A high efficient current control strategy of the Stirling linear generators was investigated in this paper. The structure of the linear generator was introduced and mathematical model was built. The efficiency of the system is compared in different current modes. The highest efficiency control strategy is calculated in the conditions of without magnetic saturation, iron-loss, mechanical loss and treating inductance as a constant. At the same time, the maximum ratio of the electromagnetic power to current control is realized. Finally, this algorithm was validated in the simulation and experiment.
