Voltage Source Inverter
Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A voltage source inverter is a power electronic device that converts a constant DC voltage into an AC voltage of variable frequency and amplitude. It typically uses pulse width modulation to synthesize the output waveform.
Example in context
“The voltage source inverter in the motor drive regulates the output frequency to control the speed of the induction motor.”
“Motor sürücüsündeki gerilim kaynaklı inverter, endüksiyon motorunun hızını kontrol etmek için çıkış frekansını düzenler.”
Where engineers use it
The voltage source inverter appears in variable frequency drives, renewable energy systems, and uninterruptible power supplies. Engineers use it to efficiently convert DC from batteries or rectifiers into adjustable AC for motor speed control or grid connection.
Synonyms: VSI
Antonyms: current source inverter
Practice: can you use “Voltage Source Inverter” at work?
