Inversores de frequência (Variable Frequency Drives - VFDs) are a direct competitor to soft starters. Both are used to control the starting and stopping of AC motors, but VFDs offer more sophisticated control over speed and torque throughout the motor's operation, whereas soft starters primarily manage the initial inrush current during startup. The increased functionality of VFDs make it a competitor, especially when precise speed control is required.
