| dc.description.abstract | 藉由調節輸入雷射二極體電流大小來控制雷射的強度，因此設計可調節電流之電源供應器作為雷射的電源供應即是本論文之目的。透過電源供應器的架構設計，提高能源的轉換效率，縮小電源供應模組的體積，並且能夠同時提供3組獨立雷射機台穩定可調變之電流源。
在本論文的系統架構中包括功率因數修正電路、相移式全橋轉換電路以及降壓型直流轉換電路。升壓型功率因數修正電路採用Texas Instruments公司所生產之型號UCC28180控制晶片，輸入電壓範圍為100~240VAC，輸出390VDC直流電至相移式全橋轉換電路。相移式全橋轉換電路採用Texas Instruments公司所生產之型號UCC3895控制晶片，利用相移技術達到零電壓切換之柔性技術。降壓型直流轉換電路中PI控制器則是由運算放大器構成類比控制器，可將單組獨立輸出電流於21.6~32A間進行調節。 | zh_TW |
| dc.description.abstract | The intensity of the laser is controlled by adjusting the magnitude of the input laser diode current. Therefore, it is the purpose of this thesis to design a power supply with adjustable current for the laser. Through the architecture design of the power supply, the energy conversion efficiency is improved, the volume of the power supply module is reduced, and three sets of independent laser machines can be simultaneously provided with a stable and adjustable current source.
In the system architecture of this thesis, a power factor correction circuit, a phase shift full bridge conversion circuit, and a buck converter are included. The boost power factor correction circuit uses a model UCC28180 control chip manufactured by Texas Instruments, with the input AC voltage range of 100 to 240 V and the output voltage to a phase-shifted full-bridge conversion circuit is DC 390 V. The phase-shifted full-bridge conversion circuit uses a model UCC3895 control chip manufactured by Texas Instruments, and uses a phase shift technique to achieve a zero voltage switching flexible technology. The PI controller in the buck is composed of an operational amplifier to form an analog controller, which can adjust a single independent output current between 21.6 and 32A. | en_US |
