The main reason for the efficiency requirements of DC power modules

Energy Saving: High-efficiency power modules reduce energy loss during conversion, saving energy and reducing waste. This is crucial in modern industrial and household appliances, especially for frequently used and energy-intensive equipment.

Heat Issues: Lower efficiency power modules generate more heat, making electronic components more susceptible to thermal damage. This is particularly true in harsh environments such as high temperature, high humidity, and high altitude, where higher efficiency is required.

Sensitivity: For applications requiring high sensitivity in the end-use circuitry, high stability of the power module's output voltage and current is essential, and the output voltage and current should be as unaffected as possible by external environmental interference. Higher efficiency is then necessary.

Reliability: Higher efficiency power modules have lower internal discharge, reducing component aging and the likelihood of failure, thus improving reliability and extending lifespan.
