【摘要】 并网逆变器既可以用于光伏发电和风力发电中,也可以用于社会生活中没有充分利用的能力的回馈电网。三相并网逆变器有三组桥臂,每组桥臂有两个IGBT,控制三组桥臂的导通状态可以改变输出波形,SVPWM正是基于此的一种控制策略。由于逆变器在设计过程中存在高电压、大电流的情况,因此有必要在系统设计之前先进行建模仿真,以期使系统的输出达到更满意的效果。更多还原

【Abstract】 Grid inverter can be used not only for photovoltaic power and wind power,but also for social life without fully used power feedback to grid.Three-phrase inverter has three sets of bridge arm,and every bridge arm has two IGBT.Controling the three sets of bridge arm can change the output waveform,and SVPWM is a control strategy based on it.For there are high voltage and large current in the process of designing,Simulink is necessary for the ideal outpun waveform of the system.更多还原
