ABSTRACT:
A stability control system for a free piston Stirling engine/alternator power unit whose engine power is an exponential function on the engine piston stroke and whose alternator power demand is also an exponential function of the piston stroke, and wherein the engine exponent is normally equal to or greater than the alternator exponent, includes a connection through a rectifier between the alternator output terminals and the alternator field windings. This increases the alternator exponent above the engine exponent to make the system stable. The large time constant of the field winding inductance, which would tend to slow the response time during transients, can be avoided by adding a suitable resistance in series with the field winding.
