Current Regulator
Item Name Code (INC) 00715
 |
A regulator that automatically controls the current output of an electric system within a specific range regardless of the variation of the effective load or input current values. Does not include items in which regulation is accomplished solely by transformer action. See also TRANSFORMER, POWER (as modified). Excludes REGULATOR, ENGINE GENERATOR.
Additional Information for Current Regulator
A current regulator is an electronic device or circuit that is used to control and maintain a constant current flow through a load, regardless of changes in the load resistance or input voltage. It is commonly used in various applications where a stable and precise current is required, such as in LED lighting, battery charging, motor control, and precision measurement systems.
The main function of a current regulator is to limit or regulate the amount of current flowing through a load. It achieves this by continuously monitoring the current and adjusting the voltage across the load to maintain a constant current value. This is typically done by using feedback control techniques, where the current is compared to a reference value and any deviations are corrected by adjusting the voltage.
There are different types of current regulators available, including linear current regulators and switching current regulators. Linear current regulators use linear control elements, such as transistors or operational amplifiers, to regulate the current. They are simple and easy to implement but may have limitations in terms of power dissipation and efficiency.
Switching current regulators, on the other hand, use switching elements, such as transistors or integrated circuits, to control the current flow. They operate by rapidly switching the current on and off, and adjusting the duty cycle to maintain a constant average current. Switching regulators are more efficient and can handle higher power levels, but they are more complex and may introduce switching noise.
Overall, current regulators are essential components in many electronic systems that require precise and stable current control. They help ensure the proper functioning and performance of various devices and circuits by maintaining a constant current flow through the load.
