Description

The Space Vector Generator block generates space vector modulation voltage signals from stator reference voltages described by α-β voltage components.

The block uses a combination of inverse Clarke transformation and Space Vector Pulse Width Modulation (SVPWM) to compute modulated DC output voltages.

This figure shows the input reference voltages and the genearted space vector modulation voltage signals:
