原理：<\/span><\/strong> <\/p>

我們已知，在回路頻率<\/span>f<\/span>＝<\/span>1/2<\/span>π√<\/span>LC<\/span>時(shí)，回路產(chǎn)生諧振，此時(shí)試品上的電壓是勵(lì)磁變高壓端輸出電壓的<\/span>Q<\/span>倍。<\/span>Q<\/span>為系統(tǒng)品質(zhì)因素，即電壓諧振倍數(shù)，一般為幾十到一百以上。先通過(guò)調(diào)節(jié)變頻電源的輸出頻率使回路發(fā)生串聯(lián)諧振，再在回路諧振的條件下調(diào)節(jié)變頻電源輸出電壓使試品電壓達(dá)到試驗(yàn)值。由于回路的諧振，變頻電源較小的輸出電壓就可在試品<\/span>CX<\/span>上產(chǎn)生較高的試驗(yàn)電壓。<\/span> <\/p>
