Z-Source Inverter Simple Boost Simulation with SPWM Control

Simulation of a Z-source inverter with simple boost control. The modulation method employs SPWM (Sinusoidal Pulse Width Modulation), where output voltage regulation is accomplished by configuring the triangular wave amplitude and reference comparison voltage. This inverter represents a commonly used power electronics converter that transforms DC voltage into AC voltage. In this simulation, the output voltage magnitude can be modified by adjusting the triangular wave carrier amplitude, while the output frequency can be regulated by changing the reference modulation voltage. The implementation typically involves generating a high-frequency triangular carrier wave and comparing it with a sinusoidal reference signal to produce PWM gate signals for the inverter switches. This straightforward boost simulation helps in better understanding the operational principles and control mechanisms of Z-source inverters, demonstrating key aspects like shoot-through state utilization for voltage boosting and SPWM signal generation techniques.
