摘　　要：二极管箝位型三电平逆变器由于其输出容量大、输出电压高、电流谐波含量小的优点而被广泛使用。由于非线性负载、死区效应等因素的影响,输出电压波形会发生畸变。此处提出了一种基于等价输入干扰(EID)的重复控制方法,在利用重复控制消除输出电压中周期干扰的同时,结合EID控制,消除输出电压非周期的干扰,并通过实验证明其可行有效。Diode-clamped three-level inverter is widely used owing to its large output capacity, high output voltage and low current harmonic.Due to the influence of nonlinear load and dead zone ,the output voltage waveform will be distorted.A repetitive control method based on equivalent input disturbanee（EID） is proposed.By eliminating the peri- odic interference in the output voltage with repetitive control, the EID control eliminates the nonperiodic interference of the output voltage.And experiments show that it is feasible and effective.
