Key points for circuit design to enhance the accuracy of "constant current control" in industrial power supplies.
Explaining the key points for improving the accuracy of constant current control while incorporating circuit methods related to constant current control!
The typical industrial power supply mainly uses "constant voltage control" to maintain a stable voltage. However, there are applications where it is essential to keep the "current" constant to ensure the quality of processes handled by machinery, such as plating, laser processing, or inspection equipment for secondary batteries for electric vehicles. In this industrial power supply, "constant current control" is more challenging compared to constant voltage control. So, why is constant current control difficult? It is because, even when the load fluctuates significantly, the voltage must be adjusted instantly to maintain the current value within milliseconds. The component that complicates this voltage adjustment is the capacitor. Normally, capacitors work to stabilize voltage, but in constant current control, they must counteract this property and continuously force the voltage to change according to load fluctuations. *For more detailed information, you can view the related links.
