| Abstract: | In view of the phase control for output voltage of auxiliary inverter in grid-connected process,rotating coordinate transformation is used to detect phase,so that the phase and frequency of auxiliary power supply and power supply grid can be obtained.Phases of auxiliary power supply and power supply grid are detected synchronously,and according to phase difference obtained,the output voltage phase of auxiliary inverter can be adjusted to guarantee in-phase between inverter output and power supply grid.The i... |
