【Abstract】 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.更多还原
