| 摘 要： | 为了满足一种新能源发电领域的电力电子变换装置上逆变器触发的要求,研制了利用OMAPL138和FPGA实现的多路PWM脉冲发生器。该脉冲发生器利用接口单元接收OMAPL138写入的PWM脉冲占空比和设置参数等数据,利用FPGA产生PWM波形,达到其工作不受OMAPL138影响的效果。同时介绍了脉冲发生器的硬件架构、基本原理和实现方法,并通过仿真和实验得到验证。该PWM发生器既简化了电路的设计,提高了系统的可靠性,又可保证逆变器功率元件触发的同步。

| Abstract: | In order to meet the inverter of trigger requirements applied to the power electronic , this paper primarily presents a novel method of using OMAPL 138 and FPGA to implement multi-channel PWM pulse generator with three-level PWM inverters .The pulse generator receives the PWM pattern parameters and setting parameters from OMA-PL138 processor through a built-in parallel interface , and produces the three-phase PWM driven signals by FPGA without the OMAPL138 intervention .The hardware architecture , basic principles , implementation method of the pulse generator described in this paper is verified by simulation and experiment .Three phase PWM generators have the fea-tures of simplifying circuit-design, improving reliability of system and guaranteeing concurrent triggering of power de-vices. |
