臺灣博碩士論文加值系統

本論文提出一具有均流弁鄐妊甈萓h模組主動電力濾波器並行系統，藉由均流機制，本系統中各模組能平均供給負載所需的無效必v與電流失真必v，可提高系統各模組的利用率和系統的可靠度、穩定度以及擴充性。在單模組主動電力濾波器的製作中，其操作模式分為全主動濾波模式與部分主動濾波模式。當單模組濾波器的輸出電流超出開關元件的額定電流時，其能動態調整其最大輸出電流至開關的額定電流，進而限定所能輸出之最大必v，避免開關元件之損毀。藉由此二種工作模式的轉換，使得單模組主動電力濾波器在其額定容量下，達到最佳的補償效果，並且提升並行系統整體的利用率。最後，本研究實際完成單模組主動電力濾波器之製作與多模組主動電力濾波器並行系統的測試，且利用電腦模擬和實測結果比較，進一步驗證此系統之可行性。

The objective of this thesis is to develop a single-phase parallel-APF system with load current sharing feature for improving power factor and reducing current harmonics. With the load current sharing feature, each APF module can provide identical power, and then, utilization, reliability, stability and expandability of the parallel system can be improved. In the proposed APF module, the operation modes can be divided into full-active-power filtering (FAPF) mode and partial-active-power filtering (PAPF) mode. If the inverter output current exceeds its switch-current rating, the APF module will dynamically limit its maximum output current to the switch-current rating. With the FAPF mode and PAPF mode, utilization and filtering performance of the APF module can be increased. Simulated and experimental results have verified that the proposed parallel-APF system can fulfill all of the pre-mentioned features.
