本論文提出了應用壓電變壓器於充電幫浦功因修正之電子式安定器上，可分為以下三種型式：電壓源型式、電流源型式、電壓電流源型式。利用壓電變壓器取代傳統連續導通模式充電幫浦功因修正之電子式安定器中的諧振槽、高壓變壓器，使得電路體積與重量大幅減少。
一般電子式安定器因為輸入電流導通角過小而有嚴重的諧波污染。傳統充電幫浦功因修正之電子式安定器雖可解決此問題，但由於電路本身的磁性元件過多，而使電路的體積較大。
本論文所提出的電路是利用壓電變壓器取代傳統充電幫浦功因修正之電子式安定器中的諧振槽和高壓變壓器，使得整體電路體積與元件數大幅減少。實驗數據驗證本論文所提出之電路皆可達高功因且功率開關在未外加串聯電感情況下可操作於零電壓切換。

This thesis presents the piezoelectric transformer (PT)-based continuous-conduction-mode (CCM) charge-pump (CP) power-factor-correction (PFC) electronic ballasts, in various types of voltage-source (VS), current-source (CS), or voltage-source/current-source (VSCS) ballasts. By replacing the L-C resonant tank and high-voltage transformer in the discrete CCM CP-PFC electronic ballasts with a piezoelectric transformer (PT), the volume and weight of the circuits can be reduced.
The main drawback of the conventional electronic ballast is that the input current has a narrow conduction angle, which causes high levels of harmonics that pollute the power system. Although the discrete bridgeless CCM CP-PFC electronic ballasts can solve this problem, these electronic ballasts still require too large a volume of magnetic devices.
Since the equivalent circuit of the PT is identical to the discrete L-C resonant tank and high-voltage transformer used in CCM CP-PFC electronic ballasts, the L-C resonant tank and transformer can simply be replaced by the PT to save the volume and weight. The experimental results show that the electronic ballasts using PT achieve high power factor and that the switches can operate under a zero-voltage-switching (ZVS) condition without any series inductor.
