摘要

常用的带PWM脉冲发生器的专用微处理器无法为多模块变换器或多电平变换器提供足够的PWM脉冲。采用现场可编程门阵列(FPGA)实现多通道PWM脉冲发生器，与多微处理器方案相比，FPGA的单芯片结构避免了同步和通信问题。为了验证所提出的多通道PWM脉冲发生器的正确性，完成了采样时间交错空间矢量调制的三相电压源级联5电平逆变器样机

FPGA Based Multichannel PWM Pulse Generator for Multi-modular Converters or Multilevel Converters

Familiar special microprocessor with PWM pulse generator cannot provide enough PWM pulses for multi-modular converters or multilevel converters. Field programmable gate array (FPGA) is applied to implement the multichannel PWM pulse generator with no synchronization and communication trouble due to the single chip structure of FPGA compared with the multi-microprocessor scheme. A three-phase voltage source 5-level cascade inverter prototype with sample time staggered space vector modulation is accomplished to verify the correctness of the proposed multichannel PWM pulse generator
