Potential improvements of power supplies were studied in the light of advancements of circuit concepts and technology of components. Two concepts were studied the FM-SS inverter and the tap switch modulation approach, which was abandoned. Progress on the FM-SS inverter was demonstrated by operation of a breadboard near rated power in conjunction with a verbal presentation. This power modulator is self-stabilizing, self-protecting, operates as an active filter section with respect to the source ripple, has automatic controlled rectifier turn-off, under elimination of commutation currents, and uses no energy-destructive damping networks. These properties indicate a lightweight, reliable power supply with relatively high efficiency. Attenuation of the source ripple by a factor four was attained experimentally by active filtering of the FM-SS inverter, and there are efforts underway for further improvement. A reduction of size and weight of at least two-thirds, compared to a conventional power supply with equal performance and efficiency, is expected.
