ABSTRACT:
A thermoacoustic array energy converter consists of heat driven thermoacoustic prime movers in parallel coupled by means of an acoustic cavity to a piezoelectric electrical generator whose output is rectified and fed to an energy storage element. The prime movers convert heat to sound in a resonator. The sound form a phase-locked array is converted to electricity by means of the piezoelectric element. The generated electric energy is converted to DC by means of a rectifier set and it is then stored in a battery or supercapacitor. The generated electric energy can also be converted to power line frequency.
