摘要： An electronic ballast (10) for powering at least one gas discharge lamp (30) includes a current-fed resonant inverter (300) and a load shed circuit (600). Inverter (300) ordinarily powers the lamp at a first level. When a load shed command is sent by the electric utility and received by an associated load shed receiver within the ballast (10), load shed circuit (600) causes the inverter to reduce the lamp power from the first level to a second level. Preferably, load shed circuit (600) includes an isolation circuit (620) and a bidirectional switch (640) that is coupled in parallel with a return ballasting capacitor (388) within inverter (300). In the absence of a load shed command, bidirectional switch (640) effectively shunts return ballasting capacitor (388), which causes the lamp to be powered at the first level. In response to a load shed command, bidirectional switch (640) ceases to shunt return ballasting capacitor (388), thereby causing the lamp power to be reduced to the second level.

摘要： A controller for a resonant inverter with a self-oscillating driver IC for powering AC loads, such as gas discharge lamps or regulated DC/DC converters, includes a timing circuit that generates control strobe pulses that are injected into the timing circuit. The timing circuit is coupled to an inverter resonant tank through a feed back circuit providing phase lock for the resonant inverter. The feed back circuit includes a passive phase shifting circuit for 360° closed loop phase shift. Phase controlled strobe pulses automatically adjust IC oscillator frequency for safe and stable inverter operation above resonant frequency. By injecting a small AC or DC control signal into the timing circuit, sync strobe pulse phase angle can be advanced or delayed and thus frequency and power of the phase lock system can be controlled.

摘要： A resonant inverter with a self-oscillating driver IC for powering AC loads, such as gas discharge lamps or regulated DC/DC converters, includes a timing circuit that generates control strobe pulses that are injected into the timing circuit. The timing circuit is coupled to an inverter resonant tank through a feed back circuit providing phase lock for the resonant inverter. The feed back circuit includes a source of variable bias current connected to an input terminal of a zero signal detector to shift an angle at which polarity changes to control a frequency for the resonant inverter.

摘要： A ballast resonant inverter with a self-oscillating driver IC powers and dims a gas discharge lamp. A feedback circuit automatically adjusts IC oscillator frequency for safe and stable inverter operation above the resonant frequency following changes in the resonant load. The feedback signal is derived from resonant inverter output voltage, by attenuating, programmed phase shifting and injecting the resulting signal in a timing circuit of the IC. The feedback circuit includes an active inverter circuit or passive RC phase boosting networks coupled in series. Phase control of the feedback signal by variable RC networks is used in transient modes of ballast-lamp operations.

摘要： Disclosed is a distributorless ignition system of inductive discharge type for internal combustion engines. This system comprises basic ignition coil means (14) for centralized supplying of inductive energy for spark plugs and trigger ignition coil means (22a, 22b, 22c and 22d) preferably disposed on spark plug heads for inducing electrical break-down across the electrodes of a spark plug. Both the basic and trigger ignition coil means are energized from a battery (10) through switching means (36a and 36b). The basic ignition coil means generates current pulses for spark plugs with respectively low voltage. The rated power of the trigger ignition coil means is provided to be much less than the same of the basic ignition coil means.
