摘要

本論文主要發展LED燈及螢光燈之通用型照明驅動器。LED的發光原理與螢光燈不同，本論文提出半橋式諧振換流器，可以同時驅動螢光燈和LED燈。首先，換流器在較高頻率下工作，以檢測燈管的類型。然後，換流器根據燈管的種類給予適當的控制。使用脈波寬度調變來調節每支燈管的功率，無論是螢光燈還是LED燈，每支燈管都可以工作在額定功率。最後研製可驅動多支燈管通用型驅動電路以驗證可行性。

This thesis presents the design and implementation of the driving circuits for LED lamps and Fluorescent lamps. The Emitting light principle of LED is different from fluorescent lamp. This thesis proposed a half-bridge resonant inverter that can simultaneously driving fluorescent lamps and LED lamps. At first, the inverter is operated by high switching frequency to detect lamp types. Then, the inverter is given appropriate control according to the type of lamps. Use pulse-width modulation to regulate the power of individual lamps. Each lamp is operating at rated power. Finally, a prototype has been implemented to verify its feasibility.
