摘要
馈能型直流电子负载作为一种新型电力电子装置,较传统的负载相比,具有节能、体积小、重量轻等特点。本文简要介绍了基于DSP芯片TMS320F2812控制的馈能型直流电子负载系统的结构、原理,重点对基于有源钳位技术的直流变换部分,采用电流滞环控制的逆变部分,以及同步锁相环节的数字化控制进行了研究,并进行了仿真验证。
Instead of traditional load system, direct current electronic load with energy recycling is much higher erefficiency, energy-saving, and smaller volume as a newly developing power electronic device. The structure and priciple which DC elcetronic load system based on TMS320F2812 has is introduced in brief, digital control technologies about DC/DC based active-clamp, DC/AC based on hysteresis current control and synchronous phase locked are also studied in this paper. At last, simulation is used for proving the edffectiveness of this design.
