AKKN ElectronicsApplication of B25615A5137J101 in Photovoltaic Inverter Field
High Temperature Tests Faced by Photovoltaic Inverters
Photovoltaic power generation systems are typically installed outdoors, and inverters need to withstand high temperature tests from intense sunlight. During summer, internal temperatures of inverters may exceed 80°C, placing extremely high requirements on capacitor high-temperature resistance. At the same time, photovoltaic inverters need to process complex MPPT tracking algorithms, and frequent power changes require filter capacitors to have fast response capabilities. Traditional capacitors have dramatically shortened lifespans in such environments, becoming a weakness in system reliability.
