In recent years, switch mode power converters have been widely used in various fields of modern electronic technology, including industrial, commercial, utility, and consumer markets. Based on low-power DC/DC conversion applications, most modern power conversions are accomplished using three main types of power converters: step-down, step-up, and step-down step-up. But in specialized applications, advanced combinations or enhanced variants of traditional topologies are often used. Although various DC/DC converter topologies can be found in literature, there is no solution that can meet the needs of all applications, so customization has become a necessary path. View >>

Where can I do secondary screening for components? Secondary screening of components is a qualification inspection conducted before the installation and use of components, with the aim of eliminating early failed products and improving the reliability of product batch use. After the acceptance of the components is qualified, the ordering unit or the user unit shall entrust the component testing station to conduct secondary screening according to relevant regulations, and it is required to remove early failed components. Secondary screening of components is a supplement to primary screening, and should comprehensively consider the usage conditions and application environment of components based on the items and stress of primary screening.
