Abstract
A 240 Watt output power SEPIC converter with an output voltage of 24 V is proposed to be used in automotive and railway LED applications. 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 56° across all input voltage values. The transients of the switch is damped using a passive snubber circuit. Electromagnetic analyses are performed using Ansys SiWave™ 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. © 2019 IEEE.
