技術說明

本發明提供一種多相反流器控制裝置及其輸出電流控制方法，至少包括離散電路接收反流器輸出電流命令連續矩陣訊號、反流器輸出電流回授連續矩陣訊號及負載電壓連續矩陣訊號，轉換成複數離散矩陣訊號，多維量化電路根據多維量化電流控制演算法，將複數離散矩陣訊號運算成反流器輸出電壓離散矩陣訊號以決定複數開關切換訊號，驅動電路接收複數開關切換訊號轉換成複數開關驅動訊號，反流器電路接收複數開關驅動訊號以驅動負載。依本發明之技術內容可產生較低切換次數之開關切換訊號來降低開關切換能量損耗，同時達成反流器輸出電流控制之目的 This invention provides a multi-phase inverter control device and its current control method. It includes but is not limited to a discrete circuit receiving three continuous matrix signals – inverter output current command , inverter output current, and the load voltage. The digital circuit also transforms the three matrix signals to a plurality of discrete matrix signals. Then, the multi-dimensional quantization circuit pursuant to a multi-dimensional feedback quantization current control (MDFQCC) by receiving the matrix of discrete signals and then generate the discrete matrix signal of output voltage of inverter to determines a plurality of switching signals. The drive circuit generate a plurality of drive signals of switch based on the received switching signals. This invention is able to reduce number of switching and increase system efficiency. It also extends the lifetime of switch and lowers the switching loss.
