一种新型Boost变换器前馈控制策略
A Novel Feed-forward Voltage Control Strategy of the Boost Converter
摘要
Abstract
In the stand-alone photovoltaic system with DC(direct current) bus-bar, stabilizing the DC bus volt-age is an important method to guarantee the efficient operation of the system, high power quality and long life of the battery. A novel topology that the MPPT of PV (maximum power point tracking of photovoltaic) boost converter and the DC bus are connected by another boost converter is proposed. Moreover, a new feed-for-ward control strategy is applied to the boost converter to stabilize the DC bus voltage: based on the voltage outer loop and current inner loop control, the input voltage and load current feed-forward loops are introduced to eliminate the fluctuation of DC bus voltage due to the change of the two factors mentioned above to improve the voltage-stabilizing performance of the system. The simulation compares DC bus voltage of double-loop con-trol and the control mentioned in this paper in case of voltage leap and verifies effectiveness of the above-mentioned control strategy.关键词
