摘　　要：随着永磁同步电机的多相化发展,电压源型逆变器的脉冲宽度调制(PWM)算法也需扩展至相应的多相PWM算法体系中。目前,常用的双三相型电压源逆变算法主要包括载波型PWM和空间矢量脉宽调制(SVPWM)等。在传统的电机控制算法中,SVPWM通常在数字信号处理器(DSP)或微控制器(MCU)中实现。然而,这类串行执行的处理器虽然对于一些对成本敏感、控制精度要求并非极高的电机控制应用场景是较为合适的选择,但在一些高性能控制场合或特殊应用领域,却会限制算法性能的提升。鉴于此,本文采用现场可编程门阵列(FPGA)来实现双三相永磁同步电机电压源逆变器PWM算法,以充分发挥FPGA高度的并行性优势和良好的移植性。With the development of multiphase of permanent magnet synchronous motors,the pulse width modulation(PWM)algorithm of voltage source inverter also needs to be extended to the corres-ponding multiphase PWM algorithm system.At present,the commonly used dual-three-phase voltage source inverter algorithms mainly include carrier-based PWM and space vector pulse-width modulation(SVPWM).In traditional motor control algorithms,SVPWM is typically implemented in a digital signal processor(DSP)or microcontroller(MCU).However,although this kind of serial execution processor is a more suitable choice for some motor control application scenarios that are sensitive to cost and do not require extremely high control accuracy,it will limit the improvement of algorithm performance in some high-performance control occasions or special application fields.In view of this,a field-programmable gate array(FPGA)is used to implement the PWM algorithm of the voltage source inverter of the dual three-phase permanent magnet synchronous motor to give full play to the advantages of FPGA’s high parallelism and good portability.
