新型脈沖氙燈起輝預燃電源的研制

摘要：本文根據(jù)脈沖氙燈的工作原理設(shè)計并研制了一種新型脈沖氙燈起輝預燃電源，該電源主電路采用推挽變換器和高頻變壓器構(gòu)成預燃電路以及利用串聯(lián)諧振起輝原理實現(xiàn)高壓起輝，具有輸出穩(wěn)定、結(jié)構(gòu)簡單、體積小、重量輕、效率高。試驗結(jié)果表明，該電源工作可靠，運行穩(wěn)定，具有很強的實用價值。 敘詞：脈沖氙燈 推挽變換器 預燃電路 Abstract：According to the operation principle of pulse xenon lamps, a new structure of power supply is presented and a new power supply has been developed. The preignition circuit consists of push-pull converter and high frequency transformer in order to ignite the pulse xenon lamp at a high pressure state with the principle of series resonance. The power supply has the characteristics of stable output, simple structure, small size, low weight and high efficiency. The results of experiment indicate that the power supply works stably and reliably and is suitable for all kinds of pulse xenon lamps.
