Description

technical field [0001] The invention relates to the field of inverters, in particular to photovoltaic inverters used in photovoltaic power generation systems. Background technique [0002] With the development of economy and society, the old energy sources are getting less and less, and the damage to the environment is gradually deepening. Human beings begin to pay more attention to new energy sources. Solar energy is an endless source of energy, environmentally friendly and hygienic, and not subject to regional restrictions, so it has become the most important future energy source, especially the use of solar energy for power generation. However, the output of photovoltaic arrays is generally direct current, which often needs to be converted into alternating current through a photovoltaic inverter before it can be used in applications. At present, the 3-phase full-bridge inverter unit used in medium and high-power photovoltaic inverters often adopts an integrated design, t...
