Description

technical field [0001] The invention relates to an inverter for a solar grid-connected power generation system, in particular to a high-power inverter. Background technique [0002] With the consumption of earth resources, people began to pay attention to the development and utilization of renewable energy. Solar photovoltaic systems have been widely valued by various countries because of their advantages of environmental protection, pollution-free, renewable, not subject to geographical restrictions, and great development potential. In the future society, Solar energy will be the main energy source. The electric energy generated by the solar power generation system is direct current, which must be converted into alternating current by an inverter before it can be output to the grid-connected power generation system. Therefore, the design of a high-power grid-connected inverter is an important indicator of the success or failure of a photovoltaic power plant construction. E...
