The types of PWM techniques are:

  1. Single pulse width modulation
  2. Multiple pulse width modulation
  3. Phase displacement control
  4. Sinusoidal pulse width modulation
  5. Space vector pulse width modulation.

 
The space vector pulse width modulation is an algorithm to control the PWM.
 
In single pulse width modulation, by comparing a rectangular reference signal of amplitude with a triangular carrier wave, the signal is generated.
 
Multiple pulse width modulation, there are multiple numbers of pulses per half cycle of the output voltage. The width of each pulse is similar and can be altered by varying the carrier signal.
