“…In the article, two switching angles (120 ο & 180 ο ) are considered for both symmetrical and unsymmetrical configurations of open-end winding induction motor drive. In centre spaced PWM (7218), zero vector is used twice in a half carrier cycle [5][6][7][8][9][10]. To generate centre spaced sequence, Inv-1 is operated in sector-1 (0 ο ), whereas Inv-2 is operated by 180 ο advance with Inv-1 as reference is shown in Fig.…”

“…Out of those, open-end winding induction motor is the one of the configuration, where we can directly get the three level output voltage with two conventional two level inverters on either side feeding half of the dc voltage to the each inverter compared to conventional multilevel inverters [1]. Due to this reduction in magnitude of input voltage over conventional multilevel inverters, common mode voltage is also reduced by high extent, which further reduces the bearing currents [10]. This paper presents the decoupled space vector based PWM techniques for both symmetrical and asymmetrical configurations of open-end winding induction motor drive.…”

Такие повреждения вызваны образова-нием в приводном электродвигателе подшипниковых токов, которое могут оказывать непрерывное или постоянное воздействие на подшипниковые узлы.…”
