摘要
Abstract
In view of different capacity inverters in parallel,the droop control parallel methods are adopted,Inverter modules with no control interconnections,without interference,output capacity is expanded,system reliability is enhanced.Also two single-phase full bridge inverters are researched.The voltage and inductance current double closed-loop control are adopted besides the drive method of the hysteresis control bipolarity PWM.The droop control parallel method is adopted.Through the analysis of principles,different capacity inverter parallel condition and droop coefficient is obtained.The new droop coefficient is also obtained by the way of power decoupling control.At last,two inverters system's static,dynamic and redundancy Characteristic and the control scheme are proved by MATLAB simulation analysis.关键词
