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.

摘要： A method of and apparatus for operating a high intensity gas discharge lamp is provided wherein the inverter circuit operates at a controlled frequency such that deleterious effects of the lamp's acoustic resonant frequencies are minimized. The inverter utilizes a transformer output with high leakage inductance. The high leakage inductance provides low loss switching operation and simplified control of lamp current during both ignition and warm-up. High frequency operation as well as judicious component design and specification reduces component count, assembled size and cost of ballast.

摘要： An apparatus and method to implement an electronic ballast for a high intensity discharge lamp having AC lamp current centered at approximately 300 kHz minimizes the ballast cost and utilizes modulation of the lamp current to avoid acoustic resonance. In order to minimize the number of additional components providing the modulation function, the ripple voltage produced by PFC circuit is fed through a capacitor to a FREQUENCY SET input of an inverter controller. The value of the capacitor can be chosen to produce the desired modulation range.
