👉 In electrical engineering, a compensator is a device that adds resistance to the output of an inductive or capacitive circuit. It's used to reduce the overall input impedance and improve the performance of electronic circuits when their current flows through a load. Compensators are crucial for maintaining high levels of stability and performance in AC power supplies, as they can also help in reducing noise and improving signal integrity. They are typically designed to be passive devices, meaning that they do not change the voltage or current
