1. It is the reason of the Charger, because the voltage of the charger is not large enough. Charger is a kind of equipment for charging other electrical appliances, using high-frequency power technology and advanced intelligent dynamic adjustment charging technology. Alternating current with constant voltage and frequency is converted to direct current by power electronic semiconductor devices.
The charger can be divided into power frequency machine and high frequency machine according to the design circuit working frequency, and can be divided into ordinary charger, battery charger, solar charger and hand charger according to the way of use. Chargers are widely used in various fields, especially in the field of life is widely used in mobile phones, cameras and other common electrical appliances.
