Technical FAQs 4

What is inverter modulation?

Modulation involves adjusting the on and off duration of inverter switches under constant input DC voltage to achieve controlled inverter output voltage. The most popular modulation technique used in inverters is pulse width modulation (PWM). Space vector modulation is often used in inverters due to its ease of implementation.

Which PWM techniques are used in two-level voltage source inverters?

This paper presents a comprehensive overview of PWM techniques for two-level voltage source inverters and provides a comparative analysis of commonly employed PWM techniques, including sinusoidal PWM, zero-sequence injection PWM, third-harmonic injection PWM, space vector modulation, and optimized pulse pattern with selective harmonic mitigation.

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.

How do you calculate the modulation index of an inverter?

Given: V DC (V) = 400V, dm = 0.8. Inverter voltage, V (V) = V DC (V) * dm V (V) = 400 * 0.8 V (V) = 320V. Suppose an inverter has a DC input voltage of 600 volts and the output voltage is measured to be 450V. Calculate the modulation index. Given: V DC (V) = 600V, V (V) = 450V.
