What is Hysteresis current control?

Hysteresis current control is a technique used in power electronics and motor control to regulate the current flowing through a system. It involves setting upper and lower current limits, allowing the current to fluctuate within this predefined band. When the current exceeds the upper limit, the controller reduces the input to bring it back within range, and conversely, it increases the input when the current falls below the lower limit. This method provides fast response times and can enhance system stability while minimizing distortion in the output waveform.
