Abstract:
An electronic power regulation control device for providing constant electric power to a load of varying impedance. The device may be operated to provide degenerative or regenerative regulation with varying load peaks. The device does not require feedback but under certain conditions feedback may enhance the performance. The basic power regulating device is a thermionic electron device wherein the voltage-current characteristic approximates the ideal hyperbolic curve of constant power. This is accomplished by combining the characteristics of a current limiting, temperature limited thermionic diode in conjunction with that of a thermionic triode in a parallel combination. It is also possible to combine the functions of a control diode of high perveance and a control diode of low perveance to also approach a characteristic curve of constant power.
