摘要
对中小功率的电子负载的研究,重点主要集中在拓扑结构和控制策略两个方面。针对传统定频单周控制在控制两级变换型电子负载中存在的问题,文章运用反馈电压调节单周控制器的工作频率,提出了变频单周控制策略,较好地解决了输出波形畸变和控制失稳的问题,并通过实验验证了所提改进控制策略的有效性。
The research on middle or small power electronic load has two key aspects,topology and control strategy.Aim at some problems emergence when traditional constant frequency OCC control the two-stage-mode electronic load,a new frequency changeable OCC control strategy is presented.As using feed back voltage to adjust the working frequency of OCC,aberration control and unsteady repression of output waveshapes has achieved.The experiment also validate the effective of this improved control strategy.
