摘要

本文提出一個以FPGA為基礎之交流感應馬達SPWM驅動控制IC之設計，可利用此控制IC驅動一個三相反流器以控制三相感應馬達之轉速。其內部架構包含四部份，分別為：一個三角波產生計數器、一個三相弦波命令產生查值表、一個比較器及一個開關死鎖時間產生器，此四部分之電路設計是以VHDL語言來實現。設計後並在Simulink、ModelSim和PSIM的共同模擬環境下，建立此交流感應馬達D-Q模型以進行模擬驗證。最後下載到一個Altera 10K FPGA邏輯元件進行實驗，模擬與實驗結果顯示此控制IC的可行性。

This paper presents the design of an FPGA-based SPWM digital control IC, which is intended for controlling the rotational speed of a three-phase ac induction motor via a three-phase inverter. The architecture of the control IC consists of four major parts: a triangular wave to produce a counter, a three-phase sine-wave look-up table to produce a reference command, a comparator, and a switch dead-time generator. All the four parts have been designed by using VHDL language. The D-Q model of an AC induction motor has also been constructed for verification of the designed SPWM digital control IC in the Simulink, ModelSim, and PSIM cosimulation environment. The designed control IC circuit has been implemented on an Altera Flex 10K FPGA logic device. Simulation and experimental results are shown to verify the viability of the proposed control IC properly.
