Research on photovoltaic grid connected micro inverter with phase control method
摘要
Abstract
As the research object of micro grid connected photovoltaic inverter, the interleaved flyback structure was used as the main circuit topology of micro inverse. The introduction of active clamp technology can absorb the transformer leakage inductance energy, improve the inverter efficiency and effectively inhibited the main power switch voltage spike caused by the leakage induct-ance of the transformer. A new control strategy was studied, which can improve the weight efficiency of the micro inverter. Using TMS320F28035 of TI company as the core control chip, a 250 W micro inverter experimental prototype was designed and made. The grid-connected current closed-loop control experiment and analysis was completed and the experimental results validate the fea-sibility of this designing scheme.关键词
