Technical FAQs 4

Which modulation techniques are used in three-phase inverters?

This paper presents a comprehensive comparison of two primary modulation techniques employed in three-phase inverters: Sinusoidal Pulse Width Modulation (SPWM) control and Space Vector Pulse Width Modulation (SVPWM) control.

What is the reference voltage for a three-phase inverter?

For a three-phase inverter modulated with simple sinusoidal references, the phase leg reference voltages are given by u t = Mcos9o and u2 = Mcos (9o-21t/3).

What is the carrier/fundamental frequency ratio of a three-phase inverter?

Hence, for a three-phase inverter, the carrier/fundamental frequency ratio must be at least 7 for the WTHD of a PWM system to be less than that of six-step modulation at M = 1.

Are three-phase inverters necessary for grid-connected energy systems?

Abstract. With the increasing utilization of renewable energy sources like solar and wind, three-phase inverters have become indispensable equipment for grid-connected energy systems, sparking significant research interest in the field of power electronics.
