Once we close among The underside switches while in the converter, that section is linked to the unfavorable dc bus and gets negative.
AC motor pace is controlled in two means – possibly by controlling the voltage or frequency. Frequency controlling presents greater control resulting from regular flux density than voltage control.
Line Drops to Zero If we turn it on and off regularly then we get a sq. wave sample among zero and most.
