1 INTRODUCTIONrnHerbicides are an essential pillar in modem agricultural practice.They are used to selectively reduce the growth of weeds in crops and natural environments.Early weed mitigating chemicals date back to Roman times and include substances as simple as table salt,sulfuric add and carbon bisulfide.However,these were non-selective,required high application rates and could be toxic not only to the target weeds but to other plants and to animals.The first major advance in the development of tailored herbicides began in the mid 1940s with the development of the first organic growth regulators such as 2,4 dichlorophenoxyacetic acid (2,4-D)[1].

由于制造工艺和器件老化等原因,不同IGBT模块之间的阈值电压会存在一定差异,并对动态不均流产生很大影响.针对此问题,首先分析了阈值电压差异对并联均流的影响机理;然后建立了阈值电压差异与开通延迟时间之间的量化关系;最后以大功率IGBT模块并联为测试对象,通过对驱动延迟时间进行补偿的方法进行双脉冲测试,验证该方法的有效性.结果表明,该方法最大可以将不均流度从14.04％降低到2.21％.
