Abstract:
     The invention discloses a solar interconnected power generation energy output maximum circuit structure in the electric system technology, which comprises the following parts: solar battery group, basic inversed unit, flexible connector and controller to form multi-level concatenation inversion topological structure, wherein the solar battery group is composed of individual solar battery board to form combination board block of 48V nominal voltage output through cascading or paralleling pattern; the basic inversion unit is composed of electric electronic switch element to form bridge-patterned circuit; the solar battery voltage is controlled by passing or breaking time of four switch elements, which makes basic inversing unit output positive, zero, negative three-conditioned step voltage within time; the flexible connector is composed of electric electronic switch, which solves cascading or paralleling relationship of inversed unit mutually through PWM strategy. The invention realizes the output of step differentiated sine AC power of system topological structure, which maximizes energy output.
