摘要

高频链路技术具有功率密度高、可靠性高、电气隔离等优点。随着现代电力电子技术的发展，其潜在优势凸显，新能源电动汽车技术的发展也在不断扩大其应用领域。研究了一种含高频链路的电动汽车无刷直流电动机(BLDCM)驱动器，即高频链路矩阵变换器。针对矩阵变换器中双向开关的特点，提出了一种适用于无刷直流电机三相六态120°导通模式的基于方波的解耦调制策略，并给出了相应的波形逻辑合成。此外，还对无刷直流电机高频链路变换器在新调制策略下的工作模式进行了深入分析。系统仿真和实验结果验证了该策略的有效性和无刷直流电机高频链路矩阵变换器的可行性。

A BLDCM Driver Based on High Frequency Link Matrix Converter

High-frequency link technology has the advantages of high power density, high reliability and electrical isolation. With the development of modern power electronic technology, highlighting its potential advantages, the development of new energy electric vehicle technology is also expanding its application field. A kind of brushless DC motor (BLDCM) driver for electric vehicle containing high frequency link, that is, high frequency link matrix converter is studied. Aiming at the character of bidirectional switch in the matrix converter, a new modulation strategy is proposed, namely decoupling modulation approach that based on square wave is suitable for BLDCM a three-phase six-state 120° turn-on mode, and the corresponding waveform logic synthesis is shown. What's more, a thoroughly analysis of the high frequency link converter of BLDCM working modes in the new modulation strategy is given. System simulation and experimental results demonstrate the validity of the novel strategy and the feasibility of high-frequency link matrix converter with a BLDCM.
