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.关键词
