摘　　要：研究者基于FPGA设计了一种三相SPWM控制器,该设计器以Altera公司的Cyclone III系列的EP3C25Q240C8芯片作为控制核心,结合直接数字频率合成技术(DDS),利用Verilog语言和LPM宏模块设计生成三相SPWM控制器.设计仿真结果以及用逻辑分析仪Signal Tap II采样显示的结果表明,该三相SPWM控制器具有调制波频率、载波频率、调制度、载波比以及死区时间均可以灵活调节的优点,生成的三相SPWM波适应性强,可方便应用于逆变电源的变频调压以及电机变频调速等领域.This paper designs a three-phase SPWM controller based on FPGA.The designer uses the EP3C25Q240C8 chip of the Cyclone III series of Altera Company as the control core and combines the direct digital frequency synthesis technology（DDS） to design the three-phase SPWM controller using the Verilog language and LPM macro module.Design simulation results and the use of logic analyzer Signal Tap II sample showed that the three-phase SPWM controller has the modulation wave frequency, carrier frequency, modulation and carrier rate and the advantage of all the dead band time can be adjusted flexibly; three-phase SPWM wave generated strong adaptability.This controller can be easily applied to variable frequency inverter power supply voltage regulator and motor frequency control of motor speed, etc.
