PWM control technology has been one of the core technology of frequency conversion technology. Analog circuit to complete from the initial triangle and the reference sine wave modulation compared to SPWM signal sinusoidal pulse width modulation to control the switching power devices start to the current all-digital solutions, complete optimization of the PWM signal output real-time online, you can say that until the So far, PWM in a variety of applications still dominant, and has been one of the hot spots. SIMULINK is a combination block diagram interface and interactive simulation capabilities for nonlinear dynamic system simulation tool. It MATLAB core math, graphics, and language-based. Using SIMULINK simulation to realize the PWM waveform can be a standard PWM waveforms, the PWM waveform analysis and teacher education has an important purpose.
