The input voltage of the converter varies between 16 V and 36 V. The stability of the converter is guaranteed by moving one of the dominant pole to lower frequency and canceling the other pole with a zero. The phase margin is higher than 560 across all input voltage values. The transients of the switch is damped using a passive snubber circuit. Electromagnetic analyses are performed using Ansys SiWave (TM) to determine voltage drop, current distribution, near and far field and resonance behavior of SEPIC converter. Measurement results indicate that the SEPIC converter is stable under various operating conditions.eninfo:eu-repo/semantics/closedAccessSEPICLED driverDC-DC ConvertersSi-WaveMOSFETLight Emitting DiodesConference Object804809WOS:000500998700122
