What is DC inverter vs inverter?
A DC inverter, also known as a variable frequency drive (VFD) or variable speed drive (VSD), is an electronic device that converts direct current (DC) to alternating current (AC) with variable frequency and voltage. It is used in a wide range of applications where precise control of motor speed and energy efficiency is critical, such as motor drives, air conditioning systems and industrial automation.
