摘要
分析并网运行PWM逆变器的换流方式 ,指出通过改变调制波的调制深度和调制相位 ,可使逆变器输入有功功率 ,也可输出有功功率 ,其功率因数都为 1。
This paper analyzes the operation modes of utility interactive PWM inverter.It is concluded that inverter can both accept and produce active power with unity power factor through adjustments of modulation index and phase.Simulation results are presented.
