Abstract :
Three different current control strategies including P+Resonant controller, PI-controller in dq0-reference frame and hysteresis controller for a three-phase-four-wire solar inverter are investigated and compared concerning their influences on the leakage current at the solar array, the grid harmonics, the step response and the resulting power losses in the power devices.
