光伏逆变中对铝电解电容器的要求(国外英文资料) The requirements of aluminum electrolytic capacitor in pv inversion Introduction: solar energy as a new energy source can provide clean and clean energy for our lives. As a result of the photovoltaic power generation system to produce current to direct current (dc), but the civil power is given priority to with ac power supply, and solar power will eventually go parallel operation, this means that solar power must be driven by inverter converts dc to ac load of household appliances. As a result, inverters play an important role in solar power generation systems. The main functions of the inverter is a variable dc voltage of the power supply input into no interference of ac sine wave output, both for equipment use, also can feedback to grid. One, the solar power generation is the requirement of the photovoltaic inverter For engineers who are familiar with power management, what is the point of designing a solar system inverter? First of all, is the use of the existing photovoltaic inverter system, they can only use 5 to 10 years, and the service life of pv panels for 25 years, become a photovoltaic inverter reliability, lowest component in the system. IRs AlbertoGuerra suggests that designers must consider the life of the photovoltaic system inverter. The solar inverter technology industry has high expectations for product life and generally guarantees 20 to 25 years of life, so it is particularly important to focus on the reliability of each component. Second, the key to improve the life of pv inverter Decided to the life of the pv inverter for the reliability of its various components, although semiconductor devices are usually reliability at that level, but for passive components are likely to be a challenge, especially in the electrolytic capacitor. The reliability of electrolytic capacitors is one of the keys to improving the reliability of photovoltaic inverters. The function of electrolytic capacitor in photovoltaic inverter The photov
