    摘要: A starting and operating circuit for high pressure discharge lamps including a pair of input terminals for connection to an alternating current supply and a pair of output terminals for connection across the lamp. A ballast inductor is connected at its ends in series between one of the input terminals and one of the output terminals and a pulse generator is connected between the output terminals. The pulse generator comprises a non-linear capacitor (NLC) and a semiconductor bipolar thyristor (commonly known as a SIDAC) connected in series, the non-linear capacitor and bipolar thyristor being connected in parallel with the discharge lamp.

    摘要: A method of operating a high intensity discharge lamp having a pair of electrodes hermetically sealed within an arc tube, the method comprising frequency modulation of a carrier waveform in the kilohertz range to provide a variable frequency AC output, and applying the AC output across the electrodes of the lamp to thereby operate the lamp in a manner which minimizes or avoids acoustic resonance effects within the arc tube. The circuit includes an inverter having a first input provided by a DC power source and a drive input coupled to a square wave carrier generator which is frequency modulated by a ramp generator. The resulting variable frequency AC output of the inverter is then coupled across the lamp electrodes.

    摘要: A ballast tester contains a DC detector, a peak voltage detector and a third harmonic detector. The DC detector determines if the ballast being tested can produce a steady DC current and is, therefore, a lag ballast. The peak voltage detector can identify the ballast as a lead ballast, while the third harmonic detector can determine if a lead ballast contains a starting capacitor.
