摘要

本文主要目的為使用Renesas RX62T微控器為核心，設計並實現永磁同步馬達之兩相調變向量控制驅動器，以減少三相變頻器上的切換損失。
本文所設計之驅動器的PWM切換頻率為10 kHz，馬達轉速範圍為150 rpm到3000 rpm，首先探討永磁同步馬達的數學模型，其次以Matlab/Sisotool永磁同步馬達控制器的設計，最後則是以RX62T實現向量控制與兩相調變技術。
由實驗結果可知與傳統空間向量調變相互比較脈波寬度調變的次數，兩相調變可減少變頻器上的切換損失，系統且於動態響應和暫態響應(不同的速度命令與瞬間加卸載)皆符合規格要求，驗證所研製之永磁同步馬達兩相調變向量控制器的可行性。

The objective of this thesis is to design and implement the vector-controlled permanent synchronous motor drives with two-phase modulation to reduce switching loss using microcontroller unit, RX62T.
The switching frequency of the designed motor drives is 10 kHz and the drives speed control range is from 150 rpm to 3000 rpm. The mathematical model of permanent magnet synchronous motor is investigated first. Then, the simulation results derived from Matlab /Sisotool software are used to confirm the design. Software is implemented using RX62T based upon the vector control theory.
Experimental results show the traditional comparisons of space vector modulation, the two-phase modulation can reduce the switching loss of inverter, show satisfied results for both dynamic response and steady state response (different speed command and transient loading and unloading) can be achieved. These results confirm the design and implementation of the vector-controlled PMSM drives with two-phase modulation.
