Proper analysis of the VFD's power and control circuit diagrams is essential for successful troubleshooting. But before starting any analysis, you must know how your system connected through VFD works and how it breathes. You must also know all components of your variable frequency drive panel. A real-world example of VFD power and control circuit diagrams for smoke extraction fan will be analyzed.
The article starts with the essential basics, VFD parameters and their configuration, interfacing, and slowly moves to the detailed troubleshooting steps. As you will learn from this article, there are many steps that need to be taken into account to complete the troubleshooting task successfully and avoid any failures.
the major challenge to some motor-driven applications was . However, the advent of reliable power electronics made it possible to control the speed of motors using variable-frequency drivers.
VFDs are widely used in many applications nowadays. The main reason is that they have greater functionality and operation capabilities compared to conventional motor drives when starting a motor.
In this article, we will discuss VFD working principle, applications, configuration, construction diagrams, interfaces with other systems, and troubleshooting.
To understand the working principle of a variable frequency driver, it is important to know what it is composed of. In other words, you need to know what leads the currents passing through a VFD of a 3-phase motor, for instance, to be changed from AC to DC and then back to AC again.
VFD comprises three main sections: Rectifier, Filters, and Inverter.
It is important to be familiar with the working principle of VFDs as they are extensively used in VFDs. VFD has greater functionality and operation capabilities than conventional motor drives, which will be explained in detail in this article.
Let's take a 3-phase load as an example to see how VFDs work. Firstly, when AC power is supplied from the mains, it directly passes through the first VFD stage - . The current passes through six diodes that convert the AC-supplied current into DC. In short, each of the three phases is connected to one pair of diodes, which only allow the peak of each phase to pass through it.
