太阳能遮荫电路;CIRCUITS FOR ANTI-SHADOWING FAULT OF SOLAR CELL

摘要

本发明系一种太阳能遮荫电路，耦接至串联连接之复数个太阳能电池单元，包括：一金属氧化物半导体(MOS)开关组，包含复数个MOS开关，每一MOS开关与相对应之太阳能电池单元并联耦接；以及一驱动单元组，包含复数个驱动单元，每一驱动单元分别输出一控制信号至相对应之MOS开关，用以控制MOS开关导通；其中，当一遮荫状况发生时，驱动单元输出控制信号至相对应之MOS开关，以控制MOS开关导通。; and a plurality of driving units, each of driving units outputs a control signal to the corresponding switch separately, the control signal is used to turn on the corresponding switch; wherein, the driving circuits output control signals to the corresponding switches and turn on the corresponding switch when a shadowing condition occurs.
