The lifetime of photovoltaic inverter is determined by the reliability of its components. Electrolytic capacitors are one of the key components to improve the reliability of photovoltaic inverters. In addition, photovoltaic inverters have high expectations for life, so there are also requirements for capacitors. Photovoltaic inverter requirements for electrolytic capacitors 1. High voltage Generally, high-power photovoltaic [...]
Variable capacitors can be divided into air dielectric variable capacitor and solid dielectric variable capacitor according to their dielectric materials. 1. Air dielectric variable capacitor The electrode of the air dielectric variable capacitor is composed of two sets of metal sheets. Among the two sets of electrodes, the fixed set is the stator, and the rotatable [...]
