Web29 de out. de 2024 · VFDs work by adjusting the frequency of the motor to adjust the rpms. To do this, a VFD will actually convert the voltage twice: 1) First, it converts our three-phase AC to DC. This is accomplished with diodes. 2) Then it cleans the DC with a capacitor. 3) Next, it will convert the DC to AC. This is accomplished with transistors acting as switches. Web8 de fev. de 2024 · Motor voltage. Output voltages are available for VFDs to match almost any existing motor voltage. However, very few, if any, VFDs have a direct 13,800-volt output for very high-voltage motors. For these cases, using a step-up transformer on the output of the VFD is often necessary to match the motor voltage.
