| Abstract |
Passive cancellation of PWM inver ter ’s adver se
effects in electr ical machine system is studied in this paper .
A PWM inver ter fed ac induction motor drive system
capable of suppressing all the adver se effects of PWM
inver ter to pr ovide a robust contr ol system is developed. A
passive electromagnetic inter ference (EMI) filter developed
for this system is char acter ized by sophisticated connection
of two small passive filter s between inver ter output and
motor which can compensate for common mode voltages
produced by PWM inver ter and between motor neutral
point and rectifier input which can suppress leakage cur rent.
As a r esult small passive filter with ability of reducing of all
the adverse effects is approached. The reduction
char acter istics of the shaft voltage, bear ing cur r ent,
common mode cur rent, leakage cur rent and EMI are
approached by simulation and exper imental results. |
