Control of Three phase inverter with carrier based SVM

Carrier-Based Space Vector Modulation (SVM) is a technique that combines the benefits of space vector modulation and carrier-based PWM.

What is Carrier-Based Space Vector Modulation?

Carrier-based SVM is a hybrid approach that:

• Utilizes a sinusoidal reference signal (like Sinusoidal PWM).
• Introduces zero-sequence injection to fully utilize the DC bus voltage (like SVM).
• Uses a triangular carrier wave for PWM generation.

It mimics space vector PWM but is implemented using conventional carrier-based modulation, making it easier to implement on digital controllers.

Advantages

• Better DC bus utilization than traditional SPWM.
• Reduces harmonic distortion.
• Easier to implement than classic vector-based SVM, especially on microcontrollers.
