An improved SVPWM method for multilevel inverters
(
IEEE
, 2012 , Conference Paper)
This paper proposes a new general Space Vector PWM (SVPWM) method for Multi-Level Inverters (MLI) based on a generalization of dwell-times calculation. The presented scheme is developed for Cascaded H-Bridge (CHB) inverter. ...
A wavelet-based passive islanding detection technique
(
IEEE
, 2012 , Conference Paper)
Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ...
A new iterative learning control method for PWM inverter current regulation
(
IEEE
, 2003 , Conference Paper)
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. PWM inverters output waveforms ...
Digital control for UPS inverters
(
IEEE
, 2003 , Conference Paper)
