A frequency inverter is a technical component that converts the electrical parameter ‘current.’ In this example, the frequency inverter converts an alternating current with a constant frequency into a voltage with adjustable intensity and rate. In a nutshell, this causes a voltage conversion. Frequency inverters are capable of powering a broad range of devices, including three-phase motors, pumps, and air conditioners. The frequency of a three-phase motor can be used to influence the speed and torque of an AC motor. This regulation does not limit a three-phase motor’s performance; rather, it increases its efficiency.
