In this paper, we would like to introduce the design of DC-AC inverter with 3KW for individual home. The inverter uses the DC-DC Boost converter with 400V output and the H- Bridge DC- AC with 220Voutput. In general, the output of solar cell swings from 150V to 400V, and the Boost DC-DC uses IC UCC2818 working at 20,9khz frequency and fix the output voltage around 400VDC. SPWM method is used to create a signal to control the H- bridge and...
