The fossil energy is limited ，and it will be exhausted someday in 也e ne缸 future. The price of the fossil energy will be higher and higher with its reduction ，and this will seriously restrict the development of production and the enhancement of peoples living standard. Renewable energy is an important resource to meet 也e energy demand of the world ，especially for China which has so many people. Solar energy resources 缸e extremely rich in our coun位y，and its application has very good prospec t. Light volt incorporation net generating system can 位ansform the solar energy into electricity energy through the solar cell bo缸d，and can change the Direct Current (DC) into Altemating Current (AC) which has 也e s缸ne frequency and phase with the cityelec住icity t挂rough the incorporation inverse transformation ，and can feed back to the elec位ical net.When the sunlight is sufficie时，也.e elec位icity supplied by the 801缸 energy can be used instead of the city net elec国city; when the sunlig汕 is not sufficient or the light volt elec创city amount can not meet the demand. the control section can automatically adjust it，and the city net elec位icity can supplement. This system is mainly used for 位ansmission line adjusting peak power plant and the rooftop light volt system. The core technology of the light volt incorpora哇。n system is incorporation inverse transformation. In this article the single-phase incorporation inversion hardware is constructed and designed. It provides the main circuit of the hardware and analyzes the functions of each p缸t and chooses the DSP chip TMS320LF2407 of TI Company as the con位。1 CPU ，and elaborates the ch
