Systems, methods, and apparatus relating to the use of Stirling engine technology to convert heat, such as from solar radiation, to mechanical work or electricity. Apparatus, systems, components, and methods relating to energy converting apparatus are described herein. In one aspect, the invention relates to the field alignment of panels and the assembly of a concentrator. In another aspect, a passive balancer is used in combination with a ring frame and other moving masses to reduce engine forces and vibration on the structure of the energy converting apparatus while maintaining properly constrained alignment of various suspended masses. In yet another aspect, the invention relates to various over-insolation control and management strategy to prevent overheating of the energy converting apparatus or components and subsystems thereof.

Stirling engine systems, apparatus and methods

In one aspect the invention relates to an electrical circuit for use with a generator having an output port, the circuit to modify one of an electric current or voltage from the generator. The circuit includes a rectifier to convert the alternating current from the generator to direct current, the rectifier having a first port and a second port, the rectifier first port in communication with the output port of the generator; and a direct current to alternating current inverter to convert the direct current from the rectifier to alternating current, the inverter having a first port and a second port, the first port of the inverter in communication with the second port of the rectifier. In one embodiment, the generator is a linear alternator positioned within an energy converting apparatus comprising a Stirling engine having a piston such that motion of the piston drives the linear alternator.
