This paper presented an implementation scheme of high frequency isolated grid-connected inverter based on TMS320F2808 control. The structure and principle of the high frequency isolated grid-connected inverter were introduced. The design of hardware and software system based on DSP,the control strategies of grid-connected based on deadbeat control and the principle of generating phase-shift driving waveforms were presented. The prototype of 1.5 kW was completed. The experimental waveforms and analysis show the control strategy and schemes are effective.
