SPWM Model Example for Sinusoidal Signal Generation

SPWM Model Example

We wanted to share an SPWM model example used in the SPWM103F-1S2P and SPWM103F-2S0P modules.

This model shows how sinusoidal waveform behavior can be represented by using PWM signal generation. In this structure, the PWM output is shaped according to a sinusoidal reference, allowing the signal pattern to follow the intended sinusoidal form over time.

Sinusoidal PWM Approach

SPWM, or sinusoidal pulse width modulation, is used when a sinusoidal signal needs to be modeled through switching pulses.

Instead of generating a fixed-duty PWM signal, the duty cycle changes according to the sinusoidal reference. This makes the method useful in applications where waveform-based control is required.

Application Context

The SPWM model is especially relevant for signal generation, inverter control experiments, motor control studies and power electronics development.

By using an SPWM-based structure, a switching system can be driven according to a controlled sinusoidal reference rather than a constant PWM pattern.

Conclusion

This SPWM model example provides a simple visual reference for the sinusoidal modeling approach used in the SPWM103F module family. It helps explain how PWM signals can be arranged to represent sinusoidal waveform behavior in development and prototype applications.
