摘要： In a microwave oven, a magnetron is powered by way of a self-oscillating flyback converter circuit, which operates at a conversion frequency controllable over a range of frequencies up to about 35 kHz. The converter circuit is powered from a DC voltage derived from full-wave-rectification and filtering of ordinary 120 Volt/60 Hz power line voltage. The output of the converter is applied to the magnetron by way of a flyback transformer.In one preferred configuration, the output fromthe flyback transformer is applied dirrectly to the magnetron--without the use of an intermediary rectifier. As a result, current to the magnetron is provided inthe form of triangularly-shaped pulses with a duty-cycle of about 60% and with a crest-factor of less than 3.5.In a second preferred configuration, the output from the flyback transformer is rectified and filtered by a capacitor-inductor combination, with the result of providing a nearly constant-magnitude current to the magnetron.

摘要： A self-oscillating half-bridge inverter is powered from a power-line-operated DC voltage source and has a series-tuned high-Q LC circuit connected across its output. A pair of fluorescent lamps is series-connected across the tank capacitor of the LC circuit. An EMI filter is positioned between the inverter and the power line, thereby to minimize electro-magnetic interference. This same EMI filter also acts to produce a control signal in case a ground fault current were to occur; which control signal is used for preventing the magnitude of the ground-fault current from exceeding acceptable limits.

摘要： In a power-line-operated inverter-type magnetron power supply having a high-Q resonant L-C circuit series-excited by the inverter and parallel-loaded by the magnetron, subject invention provides for cost-effective means to prevent the destructive overload of the inverter and/or the L-C circuit that may occur during the brief period before the magnetron cathode becomes incandescent. In this power supply, the unfiltered pulsed DC output of a full-wave power-line-supplied rectifier means is applied to a pair of inverters: an auxiliary inverter for heating the magnetron cathode, and a main inverter for providing the main magnetron power. The auxiliary inverter starts operating immediately upon application of power from the power line, and therefore immediately starts the process of cathode heating. The main inverter, however, is not started until after the cathode has reached incandescence, at which time the magnetron will adequately load the series-resonant L-C circuit and thereby prevent such destructive overload.

摘要： In an inverter-type fluorescent lamp ballast, the inverter is powered from an ordinary electric utility power line by way of a rectifier means providing to the inverter a DC voltage having magnitude variations of about plus/minus 30% occurring at twice the frequency of the power line voltage. The inverter's output is a squarewave voltage of frequency averaging about 30 kHz and with amplitude modulations of about plus/minus 30%; which squarewave voltage is applied to a series-tuned L-C circuit. The fluorescent lamp is connected in parallel with the tank capacitor of this L-C circuit, thereby being provided with a current of magnitude proportional to the magnitude of the squarewave voltage. Within a significant range, the magnitude of the lamp current is a sensitive function of the frequency of the squarewave voltage; which frequency is modulated in such a way as to compensate for the variations in lamp current that would otherwise result from the amplitude modulation on the squarewave voltage. As an overall result, the crest factor of the lamp current is kept at a relatively low level in spite of the relatively large variations in the magnitude of the DC voltage.

摘要： An inverter-type ballast has built-in differential current transformer operative to sense any substantive difference in the currents flowing from each of its two output terminals. If a substantive difference exists for more than just a brief period, a trigger circuit operates to disable the inverter, thereby to remove voltage from the output terminals.

摘要： A self-contained electronic wall switch actuator can easily be mounted directly onto the outside of the face plate of an ordinary wall switch. When so mounted, the actuator engages the wall switch's actuating lever and permits the automatic actuation of the wall switch by way of simple touch action: (i) by lightly pressing a Bypass Key, the wall switch is caused to reverse its state from ON to OFF, or from OFF to ON, whichever is appropriate; (ii) by lightly pressing a Delay Key, the wall switch is caused to enter its ON-state and to remain there for a presetable first period of time; and (iii) by lightly pressing a Cycle Key, the wall switch will, starting right then and repeatedly every 24 hours thereafter, enter its ON-state for a presetable second period of time.The actuator comprises a small battery, a miniature electric motor with a gear/linkage mechanism operable to engage with and to move the wall switch's actuating lever between its OFF and ON positions, and a quartz-clock-based programming means.

摘要： A full-bridge inverter comprises two pairs of switching transistors and is conditionally operable to self-oscillate in either of two modes: a first mode wherein one of the two pairs of switching transistors self-oscillates in manner of a half-bridge inverter and powers a first load, and a second mode wherein both pairs of transistors self-oscillate in manner of a full-bridge inverter and then powers a second load in addition to the first load.Such a dual-mode inverter has utility in situations where a load has to be pre-conditioned with a relatively small amount of conditioning power (such as cathode heating power) before being ready to absorb its main operating power. Typical examples of such loads are magnetrons and fluorescent lamps.

摘要： A push-pull inverter is supplied from an inductively current-limited DC voltage source by way of a center-tap on a transformer having significant inductance. This transformer inductance is parallel-coupled with a capacitance means. The inverter is made to self-oscillate through positive feedback provided by way of a saturable current transformer. The inverter frequency is determined by the saturation time of this current transformer, which saturation time is designed to be longer than the half-cycle period of the natural resonance frequency of the transformer inductance combined with the capacitance means. The resulting inverter output voltage may be described as a sequence of substantially sinusoidal half-cycles interconnected with periods of zero-magnitude voltage. By controlling the length of the saturation time, the effective magnitude of the inverter output voltage is controlled, thereby permitting control of the amount of power provided to a load connected thereto.

摘要： A master power track is mounted along the periphery of a suspended ceiling. Plug-in-connected with this master track are light-weight modular power tracks serving as grid members of the suspended ceiling. The master track, which also serves as the conventional L-bar for the suspended ceiling, is provided with a relatively high frequency voltage; which voltage is then available at any point along the individual modular power tracks. The modular power tracks also serve as the T-bars of the suspended ceiling. Ceiling panels and light-weight fluorescent lighting fixtures are placed in the suspended ceiling grid structure, with each lighting fixture being plug-in-connected with one of its adjacent modular power tracks. The plug-in connection is accomplished below rather than above the ceiling; which implies that the space above the suspended ceiling may safely be used as air plenum. However, by using grooved ceiling panels and special connect means, the resulting ceiling is completely conventional in appearance. The fluorescent lighting fixtures are particularly light of weight due mainly to the fact that they are powered by high frequency voltage; which high frequency voltage permits the use of fluorescent lamp ballasting means of greatly reduced weight. Thus, there is provided a suspended ceiling wherein the light-weight lighting fixtures are readily installed and/or moved by simple plug-in connections, without requiring the services of a licensed electrician, yet in a manner that complies with the National Electrical Code.
