In this thesis, the design scheme of a DSP-controlled inverter applied in mobile generator is presented at the beginning and then the design method of control system is mainly discussed. Equivalent output impedance model of instantaneous voltage and current closed-loop controlled inverter is established on the foundation mentioned above. How the values of LC filter, parameters of PI regulator and feedback coefficient etc. affect the external characteristic of inverter is analyzed in detail. Non-linear factor of inverter are also discussed and corresponding solutions are put forward.
