摘要
文章介绍一款太阳能光伏发电一体化系统的设计过程,此系统由太阳能电池、蓄电池、充放电控制系统、逆变系统、外装箱体等组成。其中逆变器采用DC-DC变换和DC-AC逆变两级结构,前级完成直流升压,后级完成直流电压逆变为220V/50Hz的交流电。另外,该一体机提供一个标准通用串行总线(USB)接口,具有为有USB接口的手机、MP3等设备充电的功能。
This paper presented an incorporated photovoltaic modules, Li-battery, controller, inverter and external packaging. sists of DC-DC converter and I）C-AC inverter, in which the former latter can convert the higher voltage to 220 V/50 Hz alternating standard USB interface which can charge the electronic equipment generating system which consists of solar cell The proposed two-stage micro-inverter con- is used for boosting input DC voltage and the voltage. In addition, the system provides a s such as eellphones or mp3.
