Pulse Width Modulation (PWM)

Implement algorithms for controlling electrical power using pulse width modulation (PWM)

Proper control of pulse width modulation (PWM) ensures efficiency and accuracy in applications such as brushless motor control, solar power inverter control, and voltage regulation. A common challenge with these applications is evaluating the correctness of the control architecture early – before committing to the expense of hardware testing.

You can develop and implement accurate algorithms for regulating pulse width modulation with Simulink modeling software, which lets you:

• Design and test your PWM control algorithms in a simulation environment
• Generate ANSI C code for real-time testing and implementation
• Integrate pulse-width modulation control algorithms into an existing code base
