Application of the GRC Stirling Convertor System Dynamic Model
ABSTRACT
The GRC Stirling Convertor System Dynamic Model (SDM) has been developed to simulate dynamic performance of
power systems incorporating free-piston Stirling convertors. This paper discusses its use in evaluating system dynamics and
other systems concerns. Detailed examples are provided showing the use of the model in evaluation of off-nominal operating
conditions. The many degrees of freedom in both the mechanical and electrical domains inherent in the Stirling convertor and
the nonlinear dynamics make simulation an attractive analysis tool in conjunction with classical analysis. Application of SDM
in studying the relationship of the size of the resonant circuit quality factor (commonly referred to as Q) in the various resonant
mechanical and electrical sub-systems is discussed.
