What Is A Charger?

Estar Industrial Group Co.,Ltd | Updated: Jun 23, 2017

  What is a charger?

  Charger (charging machine) according to the design circuit operating frequency to divide, can be divided into power frequency machine and high-frequency machine. The Power frequency machine is the traditional analog circuit principle to design,charger machine internal power devices (such as Transformers, inductors, capacitors, etc.) are large, generally in the larger operating with a small noise, but the model in the harsh environment of the power grid resistance to strong performance, reliability and stability than high-frequency machine.

  And the high-frequency machine is the microprocessor (CPU chip) as the processing control center, is a complex hardware analog circuit in the microprocessor, software program to control the operation of UPS. So, the volume is greatly reduced,charger the weight is greatly lowered, the manufacturing cost is low, the price is relatively low. The inverter rate of high-frequency machine is generally above 20KHZ. However, the high frequency machine can withstand poor power grids and environmental conditions, and is more suitable for the stable and less dusty, warm/humid environment.

  High frequency machine and power frequency machine comparison: small size, light weight, high operating efficiency (low operating cost), low noise, suitable for office space, cost-effective (equal to low price), the impact on the space, the environment is small, relatively speaking, high-frequency charger on copiers, laser printers and motors caused by the impact (spike) and transient response (transient) susceptible,charger because the power frequency machine transformers to the mains and load isolation, to the bad environment, Power frequency machines provide safer and more reliable protection than high-frequency functions, in some cases, such as medical, and so on, the charging machine is required to have isolation devices, so the industry, medical, transportation and other applications, Power frequency machine is a good choice. The choice of the two should be based on the customer's differences, installation environment, load conditions, and so on.
