Abstract
Conference Title: 2017 Nineteenth International Middle East Power Systems Conference (MEPCON) Conference Start Date: 2017, Dec. 19 Conference End Date: 2017, Dec. 21 Conference Location: Cairo, Egypt Pulse width modulation (PWM) rectifiers can be used to regulate the input power quality of variable frequency drives (VFDs). While current techniques like passive filtering and current injection networks suffer from bulkiness, complexity, and performance issues at light loads. PWM technique provides less load-dependent performance. This paper introduces a study of improving the input power quality of a single phase to three phase rectifier-inverter structured VFD by using bridgeless dual boost (BLDB) PWM converter. Design and simulation of the proposed AC-DC converter are provided.
