Abstract:
A Stirling cycle machine control system, comprising:an energy converter having a moving member;a detector operatively associated with the moving member and configured to detect stroke of the moving member;a converter circuit coupled with an output of the energy converter and operative to convert the output from AC to DC;a regulator coupled with the converter circuit and a useful load and operative to regulate DC voltage;a controllably variable load member coupled to the converter circuit and operative to adjust load to the energy converter so as to regulate power output of the energy converter which in turn controls movement of the moving member; andcontrol circuitry signal coupled with the detector and the load member, configured to receive a feedback signal correlated with the detected stroke of the moving member, and operative to adjust load on the energy converter to limit stroke of the moving member below a threshold level.
