摘　　要：从采用滞环比较方式跟踪指令电流信号出发 ,推导出电流跟踪型逆变器中输出电感值的估算公式。通过仿真 ,验证了该公式的正确性。采用本方法选取的电感值 ,可使跟踪电流纹波以及开关元件的开关频率不超过规定值 。The paper finds out a formula to estimate the inductance value of current following inverter on the basis of tracking instruction current signal by hysteretic comparison. The rationality of this formula is proved by simulation. Adopting inductance value gained by this method can limit the ripple of following current and the on-off frequency of the switch component under the prescribed value and the system will gain nicer real-time performance.
