1. Internal structure
Multi device charger, also known as a charging adapter, is a device that converts alternating current into direct current. Its internal structure mainly includes components such as transformers, rectifiers, filters and voltage regulators.
Transformer: Responsible for converting alternating current into low-voltage alternating current, providing the necessary voltage for subsequent rectification and filtering.
Rectifier: Converts low-voltage alternating current into pulsating direct current to provide energy for battery charging.
Filter: Eliminates the AC component in the rectified pulsating DC power to make the output voltage more stable.
Voltage regulator: ensures stable output voltage and avoids voltage fluctuations caused by input voltage fluctuations or load changes.
