Variable frequency and voltage (obtained from an inverter) is the principle of autonomous control in this type of equipment. To implement the power conversion, DC-AC inverters usually apply the Pulse Width Modulation (PWM) technique. PWM is a useful technique wherein switches like Power MOSFETs are.
Basically, SPWM which stands for sine wave pulse width modulation, is a type of pulse modulation where the pulses are modulated to simulate a sinusoidal waveform, so that the modulation is able to attain properties of a pure sine wave. To implement a SPWM the pulses are modulated with an initial.
Below is the SPWM I produced with 50 Hz sine wave and 5 kHz carrier signal. I will use the SPWM signal to drive the MOSFETs in my inverter. As it is known, duty and period are constantly changing in SPWM. Since the period is constantly changing, I cannot make a precise calculation about the.
The three major carrier-based PWM techniques include triangular, sinusoidal, and sawtooth. These PWM methods offer a share of advantages and drawbacks in handling harmonic distortion, affecting their suitability in different high-voltage applications, further necessitating the need for comparative.
By comparing the frequency of the triangular carrier wave with that of the sine control wave in Fig. 4, we find that the sine control wave is divided into numerous driving signals within one cycle. The following approximate equations are used to calculate the pulse width and carrier wave frequency.
In SPWM, a sine wave is compared to a triangle wave. The switching points are generated by intersecting the triangular carrier wave of frequency fc with the reference modulating sine wave of frequency fm. The output voltage is proportional to the size of the sine wave, and the output frequency i
