摘要:针对有源中点钳位五电平(ANPC-5L)逆变器在g-h坐标系的空间矢量脉宽(SVPWM)算法下的悬浮电容电压和直流电容中点电压发散问题,提出了一种建立边沿触发脉冲控制开关状态时间的方法,降低悬浮电容电压波动,减小直流侧电容电压偏移。通过悬浮电容电流波动导致悬浮电容电压偏移的原理,依据不同开关状态下输出相同的电平,且...

针对五电平有源中点箝位型(5L-ANPC)逆变器在电网中的应用，提出一种载波移相调制下输出电压谐波的解析计算方法。首先将5L-ANPC逆变器等效为电容箝位型三电平级联逆变器，然后进一步等效为两电平H桥级联逆变器。根据叠加关系及两电平输出电压谐波的解析表达式，推导出5L-ANPC逆变器输出电压谐波的解析表达式。仿真与实验...

死区效应有源中点箝位型五电平(ANPC-5L)逆变器的死区效应会导致相电压跨电平状态的跳变,跨电平的脉宽调制(PWM)波经过长电缆传输至电机侧又会产生将近2倍的过电压,严重影响设备安全.传统以相电流极性为基础的死区效应消除方法对传感器的精度要求较高,且在电流过零点附近极易出现误判.针对上述问题,提出了一种无...
