In high-power inverters, PWM modulation is determined based on the switching frequency. Essential Switching Frequency (ESF) methods and High Switching Frequency (HSF) methods are among the modulation techniques used in controlling these converters.
This paper presents a comprehensive comparative analysis of various PWM techniques employed in multilevel inverters, including sinusoidal pulse width modulation (SPWM), space vector pulse width modulation (SVPWM), carrier-based pulse width modulation (CBPWM), and selective harmonic elimination (SHEPWM).
Pulse Width Modulation (PWM) inverters offer several significant benefits over traditional square wave inverters: Precise Control: They provide exceptional control over output voltage and frequency, which is crucial for sensitive electronic devices and efficient motor control.
PWM enables precision in wave generation and power quality and provides efficient harmonic suppression. Through the modulation of the width of the voltage pulses, the desired AC waveforms in high-voltage inverters can be approximated for an efficient and smooth power flow to the loads.
