1 How VFDs work

A VFD consists of three main components: a rectifier, an inverter, and a controller. The rectifier converts the alternating current (AC) from the power source to direct current (DC). The inverter converts the DC back to AC, but with a variable frequency and voltage that can be adjusted by the controller. The controller is the brain of the VFD, which receives input signals from sensors or operators, and regulates the output of the inverter according to the desired speed and torque of the motor.

Some of the latest trends and innovations in VFD technology are:- 1) Sensorless Vector Control: VFDs with sensorless vector control algorithms are becoming more prevalent these days. This control method allows for precise control of motor speed and torque without the need for additional feedback sensors, reducing system complexity and cost. 2) Wide Bandgap Semiconductors: The adoption of wide bandgap semiconductor materials, such as Silicon Carbide (SiC) and Gallium Nitride (GaN), is increasing in VFD design. These materials offer higher switching frequencies, lower switching losses, and improved thermal performance compared to traditional silicon-based devices, leading to more efficient and compact VFDs.

2 Why VFDs are useful

Variable Frequency Drives (VFDs) offer many advantages for industrial applications, such as energy savings, process control, and protection and safety. VFDs can adjust the speed and torque of the motor to match the load demand, thereby reducing energy consumption and operating costs. Furthermore, they can vary the speed and torque to optimize the performance and quality of a process, such as flow, pressure, temperature, or level control. Finally, VFDs provide soft start and stop, overload protection, and fault detection to prevent damage to the motor and equipment and enhance the safety of operators and the environment.

Les variateurs de fréquence se démocratisent et sont très intéressants pour un bon nombre d'applications. Installés en amont d'un moteur comme un ventilateur, ils permettent: - De diminuer la consommation électrique si l'on a pas besoin d'un fonctionnement à puissance maximale (idéal à l'ère de la sobriété énergétique) - De diminuer le niveau sonore - De réduire le courant de démarrage (particulièrement utile si fonctionnement sur une source de secours type groupe électrogène) - De réguler la vitesse de rotation du moteur en fonction d'une donnée entrante (température d'une pièce, température d'eau,...) - Réduction du stress sur le moteur par rapport à un démarrage direct

3 How to choose a VFD

When selecting a VFD for a specific application, there are several factors to take into account. For instance, the VFD should be compatible with the motor characteristics such as power rating, voltage, speed range, and insulation class. Additionally, it should be able to handle the load requirements, including constant or variable torque, steady or dynamic load, and starting and stopping frequency. Moreover, the VFD should be suitable for the ambient conditions, such as temperature, humidity, dust, noise, and vibration. Lastly, it should have the necessary features and functions to meet the control and communication needs like speed and torque control modes, feedback and display options, and network and interface capabilities.

Selecting the VFD for some applications can be straight forward some of these are pump and fan. Other applications like winch, centrifuge, winders ect can be on the more complicated side. Typical variable torque loads like pumps and fans with the motor nameplate information the correct current rating can be selected. Environmental conditions information will assist in selecting the correct enclosure rating and derating if needed. And then its about options like communications, safety, braking ect. The more complex applications you need the same information as I noted for the more simple applications but also a lot more. Duty cycle, certifications, special firmware ect. The key is to discuss with your drives partner if you are unsure.
