Pulse Width Modulation (PWM) scaling is used to scale down the voltages computed from the Field Oriented Control (FOC) to fit within the PWM carrier wave magnitude range. It also adds a bias to shift negative voltages to positive level.

Features and Benefits
- Core Functionality :
- Scales down voltages from the FOC to fit within the range of the PWM carrier wave.
- Adds a bias to convert negative voltages to a positive level.
- Operates in per unit, where 2^16 represents rated values.
- Space Vector Modulation (SVM) Integration :
- Incorporates a voltage boost provided by the space vector modulation.
- Timing and Computation :
- Computes the PWM based on the specified PWM frequency.
- A new computation can only be triggered after the previous one is complete.
