Abstract:Output voltage of the inverter can be obtained without steady state error using proportional-resonant (PR) control. The characteristics of digital resonant controller under two discrete forms are analyzed and compared, and it finally comes to be used with impulse invariant method. Double-loop control strategy based on PR control is designed detailedly in the discrete region. In order to reduce the influence of nonlinear load on output voltage, several harmonic resonant controllers are adopted. Both theory analysis and experimental result show that the inverter based on PR control has superior output characteristic using this method.
