    摘要: An apparatus for combining outputs of serially connected high frequency power sources includes a number of input ports, an output port, and a power combination structure. The power combination structure includes two outer conductive layers which extend from the input ports to the output port and one or more intermediate conductive layers which extend from the input ports to a power combination region. High frequency power from the input ports propagates to the power combination region and therein combines vectorially. The sum of the individual input power levels then propagates to the output port. The power combiner can be reversed and used as a power divider operating into serially connected loads. A preferred embodiment, including two copper clad dielectric members and an aluminum base, operates at about 915 MHz. The power combiner can be constructed in a coaxial configuration.

    摘要: A light source includes an electrodeless lamp having a generally cylindrically shaped envelope made of a light transmitting substance. A volatile fill material, enclosed within the envelope, emits light upon breakdown and excitation. A termination fixture has an outer conductor disposed around its inner conductor, both conductors having a first end which couples power to the lamp and a second end coupled to an alternating current power source. A first end of conductive means is coupled to the first end of the inner conductor, a second end of the conductive means being open-circuited. The conductive means has an electrical length whereby axial electric field maxima and minima occur thereon. The envelope is oriented centrally and axially within the conductive means so that an axial, non-toroidal arc occurs within the envelope, but does not attach to its interior walls, thereby enhancing the life of the lamp. The conductive means can be formed in a helical or spiral configuration. The spiral configuration can take various forms, such as constant or continuously varying. A small spherical conductor can be affixed to the second end of a helical conductive means to inhibit electrical breakdown from an otherwise sharp end.A power source operates at a frequency having a wavelength .lambda..sub.o. The discharge is contained in an envelope (having an internal length substantially n halves of an axial wavelength .lambda..sub.z) centrally located within the spiral conductive means. Axial electric field minima occur distances 2n.lambda..sub.z /4 from the open circuited end of the conductive means (i.e., at the ends of the envelope) and an axial non-toroidal arc occurs within the envelope but does not attach to its interior wall. If the outer conductor circumferentially surrounds the spiral conductive means and the envelope therewithin to form a cylinder having a radius b, and the spiral conductive means includes a coil having a radius a and a constant pitch p then ##EQU1## With certain designs, a plurality of arcs can occur within the envelope. An electrodeless lamp having a generally cylindrically shaped envelope with an internal length n.lambda./2 (wherein n is a positive integer) can be excited by providing an electric field consisting of a voltage standing wave with points of axial electric field minima separated from each other by a distance .lambda./2, and orienting the lamp with respect to the field so that the opposed ends of the lamp are aligned with different points of the axial electric field minima, so that an axial, non-toroidal arc occurs within the envelope but does not attach to its interior wall.

    摘要: In a light source excited with power at a high frequency, an electrodeless lamp is located in a termination fixture comprising an inner and outer conductor, the lamp being located at the end of the inner conductor. An internal tuning element is located within the fixture for creating a resonant condition when the lamp is to be started to create a maximum electric field for initiating breakdown and excitation of the fill material within the lamp. The tuner may comprise a variable capacitance coupled in parallel across the conductors at the power input end of the fixture or a variable inductance connected across the conductors at the lamp end of the fixture.

    摘要: Radioactive materials are used to assist in starting a discharge in an electrodeless light source. The radioactive emissions predispose on the inner surface of the lamp envelope loosely bound charges which thereafter assist in initiating discharge. The radioactive material can be enclosed within the lamp envelope in gaseous or non-gaseous form. Preferred materials are krypton 85 and americium 241. In addition, the radioactive material can be dispersed in the lamp envelope material or can be a pellet imbedded in the envelope material. Finally, the radioactive material can be located in the termination fixture. Sources of alpha particles, beta particles, or gamma rays are suitable. Because charges accumulate with time on the inner surface of the lamp envelope, activity levels as low as 10.sup.-8 curie are effective as starting aids.

    摘要: A solid state microwave power source for providing microwave power to excite an electrodeless lamp is designed so as to provide an acceptable impedance matching characteristic during lamp warm-up when the lamp impedance is high and changing with temperature to provide sufficient power to the lamp during the running state when the lamp impedance is matched to the source. The microwave power source includes a dc power source providing power at variable levels, a microwave oscillator receiving the dc power to produce a microwave signal, and a microwave power amplifier. The oscillator has a transistor in a common base configuration, a microstrip capacitive feedback element to sustain oscillations, and an output impedance matching arrangement formed from microstrip. The microwave signal is amplified in the solid state power amplifier having a power transistor in a common base configuration. An impedance matching section between the amplifier and the input of a termination fixture for the lamp includes a length of transmission line which transforms the input impedance of the fixture to a level at the collector of the power transistor in the amplifier so as to maximize the power delivered to the lamp at reduced power levels while maintaining the collector voltage within a safe limit.

    摘要: Apparatus for repeatedly generating a staircase ramp voltage pulse on a bus connected to a capacitive load employing a set of DC voltage sources, each producing a voltage of a step in the staircase ramp voltage. A storage capacitor is connected between the output terminal of each voltage source and ground. An FET switch is connected between each of the output terminals and the bus and between ground and the bus. A timing circuit closes each of the FET switches in order to produce a staircase ramp voltage on the bus charging the capacitive load. When it is desired to discharge the capacitive load, the timing circuit then closes the switches in reverse order. Each storage capacitor is charged by the discharging capacitive load to a voltage above the voltage of its associated voltage source. The energy thus stored is used during the next cycle to contribute to the energy required to charge the capacitive load on the bus.
