The charger is a charging device with high frequency power supply technology and advanced intelligent dynamic adjustment charging technology. Charger can be divided into power frequency machine and high frequency machine according to the working frequency of the designed circuit.
The power frequency machine is designed based on the traditional analog circuit principle. Power supply equipment inside the machine (such as transformer, inductor, capacitor, etc.). ).) are relatively large, and generally the noise is very small when running under heavy load. However, the machine has strong resistance in the harsh power grid environment, and its reliability and stability are better than those of the high frequency machine.
