Power Factor Correction in Modified SEPIC Converter fed Switched Reluctance Motor Drive


This project displays a dual output PFC (Power Factor Correction) converter for switched reluctance motor (SRM) drive. Here, an adjusted SEPIC (Single Ended Primary Inductance Converter) converter is proposed for extensive variety of speed control and to accomplish control factor redress at AC mains. The switching frequency of the converter is considered at 20 kHz.

The converter is intended to work in DCM (Discontinuous Conduction Mode) of task, which decreases the span of the output inductor. The DCM mode to acquire PFC, additionally decreases the sensor necessity when contrasted with CCM where two voltage sensors and one current sensor, add to the drive cost. The drive is proposed for all inclusive AC mains (90V-270V AC). Reenacted and exploratory results are shown to approve the execution of the drive during various working conditions. The info current aggregate consonant mutilation (THD) is decreased to go along an IEC 61000-3-2 standard.
