研究目的
To improve output performance of photovoltaic power generation systems by proposing a two-phase six-state Pseudo-Continuous Conduction Mode (PCCM) interleaved boost converter.
研究成果
The two-phase interleaved Boost converter is half the output ripple of the non-interleaved Boost converter. The PCCM eliminates the zero point of the right half plane of the converter, reduces the design difficulty of the control loop, and improves the response speed of the system. The efficiency of the converter can be improved by using the DRC control strategy, and the efficiency is inversely proportional to the duty D3 of the freewheeling phase.
