Yes, a VFD (Variable Frequency Drive) can be used as an inverter, and in fact, that’s exactly how it works internally. A VFD converts incoming AC power into DC and then inverts it back into a controlled AC output with variable frequency and voltage. This function allows the VFD to control the speed, torque, and direction of an AC motor. Both Mitsubishi VFDs and Delta VFDs are widely used in industries for this purpose, as they offer efficient motor control, energy savings, and smooth acceleration or deceleration of machinery.
When you use a Mitsubishi VFD, it acts as an inverter by regulating the output voltage and frequency to match the motor’s requirements. This makes it perfect for applications like conveyors, pumps, fans, and HVAC systems, where precise speed control is essential. Similarly, a Delta VFD performs the same inverter function, converting DC to AC while maintaining stable performance and protecting motors from electrical stress. Both brands include advanced features like vector control, overload protection, and communication interfaces for integration with PLCs or HMIs.
So yes, a VFD can be used as an inverter because its core function is to convert DC into adjustable AC power for motor speed control. Devices like Mitsubishi VFDs and Delta VFDs serve as high-efficiency inverters designed for industrial automation, offering smooth control, energy efficiency, and reliable motor performance across a wide range of applications.
