| Summary: | In this study, an interleaved boost serial resonant converter with a high transformation ratio is proposed. The main architecture of this converter is a boost converter serial resonant converter, the first stage utilizes an interleaved boost converter to reduce input current ripple, In the second stage, a resonant converter is used, where power MOSFETs and rectifier diodes enable soft switching at an appropriate operating frequency. This feature improves efficiency by reducing losses caused by the hard switching of traditional circuits. Finally, this converter is designed with the rated power of 1.5kW and the digital signal processor TMS320F28335 is employed as the main system controller core to realize the wide output voltage range <inline-formula> <tex-math notation="LaTeX">$40\sim 125$ </tex-math></inline-formula>V from fuel cell as an input power source which can output a 400V for output load or DC bus applications through the proposed converter. The experimental results show that the maximum conversion efficiency of this converter when operating at the low input voltage 40V is up to 92.69%, and at the high input voltage 125V is up to 93.57%. |
