What Is A Charger?

Shenzhen GEO Technology Co.,Ltd | Updated: Jun 22, 2017

  What is a charger?

  Charger according to the design circuit operating frequency to points, can be divided into frequency machine and high frequency machine. Frequency machine is based on the traditional analog circuit principle to design, the machine internal power devices (such as transformers, inductors, capacitors, etc.) are larger ,charger Generally in the load with a large operation there is a small noise, but the model in the harsh power grid environment resistance to strong resistance, reliability and stability than the high frequency machine strong.

  The high-frequency machine is a microprocessor (CPU chip) as a processing control center, is the complex hardware analog circuit burned in the microprocessor, the software program to control the way the UPS operation.Therefore, the volume greatly reduced, Weight is greatly reduced, the manufacturing cost is low, the price is relatively low.charger High frequency machine inverter frequency is generally above 20KHZ. But the high frequency machine in the poor power grid and environmental conditions, tolerance is poor, more suitable for the grid is stable and dust Less, temperature / humidity suitable environment.

  High-frequency machine and frequency machine comparison: small size, light weight, high operating efficiency (low operating costs), low noise, suitable for office space, cost-effective (under the same power, low price), space, environmental impact Small, relatively speaking, high-frequency charger on the copier, laser printer and motor-induced shock (SPIKE) and transient response (TRANSIENT) vulnerable to the frequency of the transformer to the mains and load isolation, the electricity In the harsh environment,charger the frequency machine provides more secure and reliable protection than the high frequency function. In some occasions, such as medical treatment, the charger is required to have the isolation device. Therefore, for industrial, medical and transportation applications, Better choice. The choice of the two according to the customer's different installation environment, load conditions and other conditions to consider.
