本研究研製一應用於微移動載具充電器(Mirco-mobility charge)之交流/直流轉換器。第一級使用功率因數修正電路進行交流/直流轉換,第二級使用半橋LLC諧振式電路進行直流/直流轉換,藉此實現交流輸入電壓110 ~ 220 Vrms,直流輸出電壓60 V,輸出電流4 A的微移動充電器。
本研究第一級電源需實現交流/直流轉換,採用升壓式功率因數修正電路使用意法半導體(ST)的控制晶片L4985A,將功率因數修正電路操作在連續導通模式。
本研究第二級電源需實現直流/直流轉換,採用半橋LLC諧振式轉換電路,使用安森美(On-semi)的控制晶片NCP13992。其次,半橋功率開關,選用意法半導體的封裝在同一個晶片上閘極驅動器與高壓氮化鎵電晶體。
本研究將第一級與第二級電路進行結合後,可將電路操作在交流輸入110 ~ 220 Vrms,皆能操作在滿載條件,並且在不同輸入條件下,功率因數皆可達到0.99,轉換效率可達到90%以上。
This thesis developed the AC/DC and DC/DC converters applied in the micro-mobility charger. The AC/DC converter was the first stage, and it can achieve the power factor correction. The DC/DC converter was the second stage, and its power topology was the half-bridge LLC resonant conversion.
The boost converter was used in the first stage, and its pulse-width modulation (PWM) controller was the L4985A (STMicroelectronics). In the second stage, the PWM controller was the NCP13992 (Onsemi), and the gallium nitride transistor was used as the half-bridge switches.
In the developed micro-mobility charger, the AC input voltage was 110 to 220 Vrms, and the DC output voltage and current were 60 V and 4 A, respectively. The power conversion efficiency can be greater than 90%.
