摘要

本文提出具相位交錯並聯永磁同步電動機之換流器設計，數位控制器送出兩組相差180度之脈寬調變訊號，使換流器脈波交錯同時達成並聯運轉。換流器模組1與模組2以相位交錯方式將切換時序錯開180度以抵消電流漣波，可降低切換頻率減少切換損失與減少對整個電力系統電磁波干擾(EMI)影響。以比例-積分控制器(PI Controller)實現電流回授控制補償，完成永磁同步電動機之轉速與電流閉迴路控制。

Parallel inverters with interleaving phase shift for permanent magnet synchronous machine (PMSM) are proposed in this thesis. The switching signals with interleaving phase shift are generated by DSP for the parallel inverters. The total current ripple can be significantly reduced by using parallel inverters with interleaving phase shift so that the switching frequency can be reduced and the power system EMI problem can be alleviated as well. Speed and current control loops are achieved by using PI Controller.
