Power Supply For Small Appliances

A charger is a common charging device that converts electrical energy into DC energy and outputs the electrical energy to electronic devices such as cell phones, tablets, digital cameras, etc. through a USB cable that connects the charger to the electronic device, thus enabling the charging process. The charger does not require the use of a computer or other device to charge, it simply needs to be plugged into a wall outlet.

Description

With the technical progress of semiconductor materials and control methods and other factors, switching power supply gradually to the direction of high power density, reliable qualitative, intelligent guest, according to the control method, switching power supply can be divided into analog power supply and digital power supply, analog power supply because of its application technology is mature, cost controllable, simple design and other advantages are widely used in small and medium power switching power supply design, with the complexity of the system design to enhance. With the increase in system design complexity, analog power supply components are complicated, poor consistency and other issues limit its development, with the high degree of integration to teach the word power supply, can be a large number of simple components scenario. This reduces the size of the system and optimizes the performance of the power supply to facilitate debugging. Digital power supply in real-time monitoring of power supply output parameters and remote control at the same time, with good dynamic performance and steady-state performance, more favored in complex systems.
