Resource Overview

This model employs hysteresis control technology, which achieves optimal output current waveform by comparing the inverter's output current with an ideal reference current. The tracking performance is excellent, typically implemented through a control loop that uses hysteresis comparators to maintain current within predetermined upper and lower bounds.

Detailed Documentation

This model utilizes an advanced technique known as hysteresis control technology. Hysteresis control is a stability-enhancing method that generates ideal output current waveforms by continuously comparing the inverter's actual output current with a reference current signal. A key component of this technique is the hysteresis controller, which effectively minimizes tracking errors and improves follow-up performance through a straightforward implementation: when the current error exceeds the hysteresis band's upper threshold, the inverter switches to reduce current; when it falls below the lower threshold, the inverter switches to increase current. This bang-bang control approach ensures system stability without requiring complex PWM calculations. Consequently, the model delivers high accuracy and robustness, making it suitable for diverse complex system control requirements where rapid current response and inherent stability are critical.
