Technical FAQs 4

What is pulse width modulation (PWM) in a high-voltage inverter?

High-voltage inverters form an essential part of renewable energy systems, and these inverters rely on pulse width modulation (PWM) to control the power conversion process. PWM enables precision in wave generation and power quality and provides efficient harmonic suppression.

Why is PWM important in high-voltage inverters?

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.

Which type of PWM is best for a high voltage inverter?

Sinusoidal PWM is the most suitable choice in high-voltage inverters and grid-tied systems due to its minimal THD, efficient harmonic distribution, and waveform quality. Triangular PWM offers moderate complexity with a balanced harmonic profile, which is best suited for general-purpose inverters and motor drives.

Why do you need a pulse inverter?

Precise Control: They provide exceptional control over output voltage and frequency, which is crucial for sensitive electronic devices and efficient motor control. By adjusting the width of pulses, these inverters can finely tune the output to match specific requirements.
