Detailed Documentation
This Simulink simulation implements hysteresis current control with PWM modulation for a three-phase inverter bridge. The model includes an additional low-pass filter stage to demonstrate how PWM signals are converted to smooth waveforms through filtering. The implementation features current feedback loops with hysteresis comparators that switch the inverter's power devices when current errors exceed predefined bounds. This approach provides automatic switching frequency adjustment while maintaining current tracking accuracy. The simulation is particularly suitable for power electronics beginners, offering practical insights into PWM generation techniques, hysteresis control algorithms, and filter design considerations through interactive parameter adjustment and waveform observation capabilities.
