ABSTRACT:
A three-phase generator is used to directly drive an array of electroacoustic transducers without the usual high power amplifiers. Complex signals having general spectra are generated by driving the generator rotor field with an excitation comprised of in-phase and quadrature components. These components are appropriately transformed so that a readily available three-phase wound rotor machine can be used without modification. The three output phases of the generator are connected to a multi-tapped delta connected transformer. Appropriate tap connection for each transducer allows achieving the desired voltage and phase angle. Freedom in choosing taps simultaneously allows balancing of the generator load.
