摘要 |
<p>An electronic ballast for a discharge lamp includes a capacitive storage device which is serially connected with an AC power source and the lamp. A first combination of switches, arranged in a bridge configuration, alternately reverse the polarity in which the capacitive storage device is connected. A second combination of switches periodically bypasses the capacitive storage device and momentarily places the AC power source directly in series with the lamp.</p> |
