An Optimal PWM Technique for Dual-Output Nine-Switch Boost Inverters with Minimum Passive Component Count
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Nine-Switch inverter (NSI) has been recently introduced for independent control of dual ac motors. Although this topology reduces the number of active switches by 25% compared to conventional inverters, it has a main ...
Performance of a five-phase boost inverter-fed submersible induction machine
(2013 , Conference Paper)
An electrical submersible pump (ESP) motor is preferably fed from a low voltage variable-frequency drive (VFD) followed by a step-up transformer. The motor and drive connection through a long feeder usually causes over ...
