In this paper we present a VLSI made of FPGA,which solves the problems of too many devices in multi-level inverter and complexity of control system, realizes the online calculation of phase angle, makes the power switch load homeostasis.

• 利用现场可编程门阵列(Field Programmable GateArray,FPGA)芯片设计一种大规模集成电路,解决了多电平变换器功率器件多、控制系统复杂的问题,实现了相角的在线计算,使各功率开关负荷动态平衡。
