摘要： A ballast (10) for powering a discharge lamp (70) comprises a source of direct current (100), an inverter (600), and an output circuit (700). Output circuit (700) provides high voltage starting pulses for igniting the lamp, and may be implemented with either a single-tapped inductor (720) or with dual tapped inductors (720,740). Preferably, inverter (600) may be realized as either a half-bridge inverter (600) or a full-bridge inverter (600′) that operates at a relatively low frequency so as to avoid acoustic resonance effects in the lamp. DC current source (100) provides a limited source of current and may be realized as either a dual current source (100) for powering a half-bridge inverter (600), or a single current source (100′) for powering a full-bridge inverter (600′).

摘要： The transmitter of the circuit breaker locator draws large amplitude, short duration, phase locked unipolar pulses of current from the power source at a frequency lower than that of the AC line frequency. The audible and visual indicators of the transmitter are triggered at the rate of the current pulses drawn from the AC line. The receiver of the circuit breaker locator has a pick-up coil that responds to magnetic field surrounding the circuit breaker, an amplifier for boosting the signal from the pick-up coil, and a single shot pulse stretcher triggered by the amplifier. The pulse stretcher drives both audible and visual signals, and at the same time charges a memory capacitor in a staircase generator fashion. The magnitude of the memory capacitor voltage in turn controls the gain of the amplifier. A switch controls the voltage applied to the amplifier, which increases by a predetermined amount when released.

摘要： FA ballast (20) for powering a gas discharge lamp (70) comprises an inverter (200) and an arc protection circuit (600). Arc protection circuit (600) monitors an electrical signal within the ballast. In response to occurrence of a disturbance in the signal, such as what occurs during output arcing, arc protection circuit (600) disables the inverter (200) for a timed shutdown period. Arc protection circuit (600) provides a timed starting period for igniting the lamp, during which time any disturbance in the electrical signal is essentially ignored and inverter (200) is allowed to continue to operate. Arc protection circuit (600) also provides a restart function for periodically attempting to ignite and operate the lamp. Arc protection circuit (600) is preferably realized using a timer integrated circuit (U1) with associated discrete circuitry, and may be adapted for use with ballasts having self-oscillating or driven type inverters.

摘要： A ballast (100) includes an inverter (140,144,146) and a protection circuit that prevents excessive lamp-to-earth-ground fault current. The protection circuit includes a transformer (202,204,206,208,210) and an inverter disable circuit (300). The transformer measures a first current going out of one set of ballast output terminals (106,108) and a second current going into another set of ballast output terminals (206,208). In response to a substantial imbalance between the first current and the second current, inverter disable circuit (300) terminates inverter switching. Preferably, protection circuit further includes a restart timer circuit (400) that, following termination of inverter switching in response to a fault condition, prevents the inverter from restarting for a predetermined delay period.

The boost converter (200) includes a boost control circuit (400) and a shifting circuit (300).

In a preferred embodiment, shifting circuit (300) comprises a shunt circuit (320) and a time delay circuit (360), and inverter (400) is a series resonant half-bridge inverter.

摘要： A ballast (20) for powering one or more gas discharge lamps (70,72,74,76) comprises an inverter (200), an output circuit (300), and an arc protection circuit (400). Arc protection circuit (400) monitors an electrical signal within the output circuit (300). When an arcing condition occurs at the ballast output connections (302,304,306,308,310), the electrical signal includes a high frequency component having a fundamental frequency that is much greater than the normal operating frequency of the inverter (200). In response to the high frequency component exceeding a predetermined threshold, arc protection circuit (400) disables the inverter (200) for a predetermined shutdown period. Arc protection circuit (400) also provides a restart function for periodically attempting to ignite and operate the lamps. Arc protection circuit (400) is preferably realized using a microcontroller integrated circuit (440) with associated discrete circuitry, and is especially well-suited for use in ballasts for powering multiple lamps via a current-fed self-oscillating inverter and an isolated parallel resonant output circuit.
