Study of a varied hysteretic-band current control technology

摘要

The inverters and control methods are applied in more and more fields with power electronics development. Thetechnology of current hysteretic band PWM is a kind of easy and reliable control method. But the harmonic distortion ofload current is big amplitude around switching frequency side band. The paper introduce a Varied Hysteretic-bandCurrent control technique(VHBCC), this method can spreads the spectrum contents of load current around switchingfrequency side band, reduces the harmonic distortion of load current . At last, The results of simulation prove the methodfeasible and effective.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
