This article will detail the working principle, classification, application fields, and usage precautions of the high-current generator.



Working Principle



The basic working principle of a high-current generator is to generate and output high current through a power supply and a current booster. The main steps are as follows:




  1. Power Input: The high-current generator obtains input electrical energy from the mains or a dedicated power supply.

  2. Current Booster: The current booster converts the input electrical energy into the required high current output. The current booster usually includes components such as transformers, rectifiers, and filters.

  3. Current Output: The high current is output to the device under test or load through output terminals.

  4. Measurement and Control: Built-in measuring instruments and control systems monitor the current output in real-time to ensure the stability and accuracy of the current.
