New Members of the PWM-Core Family: SPWM103F Modules

SPWM103F SPWM Core Structure

New members of the PWM-Core family, SPWM103F-2S0P and SPWM103F-1S2P, have been introduced.

The SPWM103F family is designed as a sinusoidal PWM core that digitally models a sine wave. The SPWM103F-2S0P version provides two SPWM outputs, while the SPWM103F-1S2P version provides one SPWM output and two standard PWM outputs.

Programmable Sinusoidal PWM Parameters

In the SPWM signal structure, the sine model parameters can be configured according to the application requirements.

The programmable parameters include frequency, sampling count and dead-time. These settings make the modules suitable for applications where sinusoidal PWM behavior must be adjusted and evaluated during development.

SPWM103F-1S2P PWM Output Features

In addition to its SPWM output, the SPWM103F-1S2P version includes two standard PWM outputs.

The frequency, phase and duty cycle parameters of these PWM outputs can be programmed separately. This provides a more flexible signal generation structure for applications that require both sinusoidal PWM and standard PWM outputs in the same module.

Communication and Configuration

The communication mechanism is designed to be simple and practical.

All control operations are performed through commands sent to the Rx pin of the SPWM103F module. The device stores all signal configurations in internal memory, so it does not need to be reconfigured at each use.

Typical Application Areas

SPWM103F modules can be used in systems where sinusoidal PWM generation or mixed SPWM/PWM signal control is required.

Typical application areas include:

· SPWM signal generation

· Inverter control experiments

· Motor control studies

· Power electronics development

· Waveform-based switching tests

· Embedded signal generation

· Prototype and R&D setups

Conclusion

SPWM103F-2S0P and SPWM103F-1S2P expand the PWM-Core family with sinusoidal PWM generation capability. With programmable sine model parameters, UART-based configuration and internal memory support, these modules provide a practical platform for SPWM-based development, inverter experiments and power electronics prototype applications.
