Third harmonic Pulse Width Modulation (PWM) is a control strategy where the switching frequency of the PWM signal is three times higher than the fundamental frequency. This technique can reduce the low-order harmonics in the output voltage waveform, leading to improved performance and efficiency in power electronic systems. By employing third harmonic PWM, it is possible to achieve better power quality and minimize harmonic distortion in the system.
