| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 103 === The thesis studies the implementation of an adjustable single-phase AC/AC converter. The hardware includes the buck-boost converter with bi-directional switches to achieve AC/AC conversion. The software is executed by using a digital signal processor, typed TMS320F2808. By measuring the feedback signals, the output voltage can keep as a constant under a variable input voltage and an external load disturbance condition. In addition, the output voltage can be adjusted according to the different input voltage commands.
The thesis focuses on the basic principle and implementation. A single-phase AC/AC converter with 90~110V input voltage, 34~220V output voltage, 150W maximum power, 0.93 power factor has been implemented. Experimental results can validate the simulation waveforms to show the feasibility and correctness of the proposed method.
