多重化CSI预充电过程研究

Research on the pre charge procedure of multiple CSI

详细分析了多重化ＣＳＩ（电流型逆变器）预充电过程以及ＢＢＣ公司、Ｓｉｅｍｅｎｓ公司的预充电控制方法，提出了采用８０Ｃ１９６ＫＢ单片机配合外围电路实现的多重化ＣＳＩ预充电控制器，给出了控制软件流程，经实验运行证明该方法具有控制灵活，结构简单，稳定可靠等优点。

The pre charge procedure of multiple CSI(current source inverter) and the method of procedure controlling of ABB and Siemens are analyzed in detail.The approach to control multiple CSI pre charge is presented based on the single chip processor 80C196KB and the peripheral hardware circuits,then the flow of the control software is given.Tests prove that the control circuit features convenient control,simple structure and reliable operation.
