    An equivalent circuit is described for the three-winding transformer which is similar in form to the classical equivalent T of the two-winding transformer. As in the equivalent T, the performance of the circuit shown can be visualized and the elements of the circuit can usually be related to specific transformer constants. It is shown that the circuit is also exact. View full abstract»

    In the VHF range, high-quality narrow-band filters with reasonable physical dimensions are extremely difficult to realize. Excessive pass-band insertion loss accompanies filters employing lumped constant elements, and unreasonable size is a natural consequence of coaxial-resonator filters. Harmonic crystal filters are inadequate because of the unpredictable amount of spurious modes above the harmo... View full abstract»

    Available relays for control of high-power direct current are seen to be large, heavy, and adversely affected by vibration and shock. This paper shows how commonly available components of reasonable size can be used with small vibration-resistant relays to control large direct currents at high potential. Thus, control of high-power airborne power supplies on the direct current side has become poss... View full abstract»

    The two-element equivalent circuit commonly used in predicting the high-frequency or pulse-front response of a stepdown or step-up transformer is not applicable to transformers with turns ratios near unity. Furthermore, the transformer leakage inductance (the series element in the circuit) may vary with frequency or time because of skin effects in the windings, and the distributed capacitance (the...
