As the energy source of many products, the power supply is an indispensable part, and many low-power power supplies are well known to everyone (such as adapters). However, high-power power supplies, including 100W to 100KW and above UPS, inverters, high-power emergency equipment, photovoltaic inverters, etc., are designed with a combination of multiple topologies, requiring test and certification engineers to have strong circuit understanding capabilities. In order to evaluate the safety and rationality of the product, and the impact of abnormal test current is large, if you do not understand the product, it will easily cause harm to the power grid, engineers, and the environment. Therefore, many third-party laboratories and institutions do not have the capacity and conditions to certify this part of the product. Our company has been engaged in certification services in this field for a long time, has accumulated rich experience, and configured corresponding equipment and testing envir
