摘要
This paper deals the comparison of soft switched push-pull type LLC series resonant converter with proposed soft-switched self-driven synchronous-rectified push-pull converter. The 48 V DC is efficiently reduced to 12 V using DC to DC converter at 20 KHz switching using both methods. Performance of proposed synchronous-rectified push-pull converter is compared with push-pull LLC series resonant converter in low output voltage applications. This converter has advantages like reduced switching loses stresses and EMI. Laboratory model of microcontroller-based DC to DC converters are fabricated and tested. The experimental results are compared with simulation results.
