    • A transformer (20) for coupling AC electrical energy from a stationary element (22) to a rotating element (24) without the use of sliding contacts. The transformer (20) is of the rotary type and includes a ferrite core (39) and two primary windings (70 and 72) which are stationary with respect to a secondary winding (88) which rotates within an annular cavity (48) adjacent an axial bore (58) in the core. The core (39) is comprised of two cup type core halves (40 and 42). Electrical connection to the secondary winding (88) is made through a split bobbin assembly (89) which couples to a coaxial shaft assembly (59) located in the axial bore (58). The electrical coupling to the coaxial shaft assembly is made through a continuous transverse channel (68) connecting the axial bore (58) with the annular cavity (48). The transverse channel (68) forms a single air gap; however, it is not open directly to free space but is shielded by the magnetic permeable material of the core halves (40 and 42).

    • A voltage regulated DC to DC converter is disclosed which is operable over a wide range of input voltage including voltages greater or less than the desired output voltage. The converter uses an inductor and a capacitor as storage elements, the inductor being composed of two windings having a common junction. A transformer having a center tap connected to the common junction of the two windings of the inductor is connected at either end of its winding to ground through controlled switches. One winding of the inductor and either end of the transformer winding are connected by respective power diodes to the capacitor which supplies the output voltage to a load. The other winding of the inductor is connected to a fourth power diode as a clamping diode. Input voltage is supplied to the inductor through a third controlled switch. A pulse width modulator connected to the output of the converter alternately closes and opens the switches connected to either end of the transformer winding and also closes the switch supplying input voltage to the inductor each time either of the switches connected to the ends of the transformer winding are closed. The duty cycle of the closing and opening of the several switches is adjusted by the pulse modulator to regulate the output voltage.
