介绍了基于固定环宽滞环电流控制的矩阵变换器的工作原理,它是将矩阵变换器等效为虚拟整流器和虚拟逆变器的串接,然后在虚拟逆变器上做固定环宽滞环电流控制;分析和推导了矩阵变换器在这种策略下的开关状态和控制规律;给出了在一个周期里,划分输入电压相区,输出电流相区的原则,确定了开关规则表;最后通过仿真得到了输出线电压和电流波形,其结果验证了文中提出的矩阵变换器控制策略的可行性。
补充资料：二尖瓣关闭不全
二尖瓣关闭不全
mitral insufficiency
由于瓣增厚、变硬、弹性减弱或瓣卷曲、缩短、腱索增粗、钙化，使瓣在关闭时不能闭合，血流反流到左房，在舒张期过多的血液又流至左室，致使心室容量增加，负荷加重，引起左心室和左心房肥厚扩张。严重者出现左心衰竭，左室舒张终末压增高，左房压亦增高，产生肺淤血，肺动脉高压，最后引起右心室肥大、衰竭。临床主要表现为心悸、气短，听诊时可闻及心尖区全收缩期杂音，呈吹风样，第一心音减弱，肺动脉区第二音亢进，晚期可出现肝脾肿大、下肢浮肿等。
