Abstract
An improved digital-controlled power amplifier for low frequency, high power applications. The circuit consists of an alternator with stator windings rewound in a binary sequence for generation of primary power, whereupon pulsed semi-conductive controlled rectifiers are digitally controlled to turn on selected binary combinations of the stator output voltages for summation to produce an output voltage of selected amplitude versus duration; and further, the summed voltage output is switched by a polarity switching bridge to enable generation of a bi-polar output to the circuit load.
