The primary inverter driving circuit,current foldback circuit,protection circuits for overheat and lowvoltage circuit are introduced specially.

重点介绍了一次逆变的驱动电路及流、、保护电路。

Photovoltaic parts: storage cell, cell charger, controller, transverter, recorder, inverter, monitor, mounting system, tracking system, solar cable etc.

蓄电池，充电，控制，转换，记录仪，逆变，监视，支架系统，追踪系统，太阳电缆等。

The traditional transformer is trending towards pocketsize and noiselessly in inverter using high-frequency link technique,but the control circuit becomes difficult to be designed.

高频链技术使逆变中变趋向于小型、无噪声化,但增加了控制电路的设计难度。
