小型户用光伏发电系统的设计

摘要

以远红外发热纤维软板为载体，设计一款户用型光伏发电供暖系统。选用PWM整流桥和boost/buck升降压斩波电路结合作为主电路，并对逆变器基本电路进行研究，采用模糊控制方法进行最大功率点跟踪。测试结果表明，该光伏发电供暖系统的节能效果比较理想，比公共电网直接供电节能23%左右。%With far infrared heating fiber soft board as the carrier, a household type photovoltaic power heating system was designed. PWM rectifier bridge and boost/buck buck chopper circuit were selected and combined as the main circuit, and study was conducted on the inverter circuit, the fuzzy control method was adopted for maximum power point tracking. The test results show that the energy saving effect of the heating system of the photovoltaic power generation is ideal, with around 23% energy saving than the direct supply by the public grid.
