WEBAug 15, 2014 · What is IGBT? An Insulated Gate Bipolar Transistor (IGBT) is a key component in what makes up a VFD (Variable Frequency Drive). If you break down a VFD, one easy way to analyze it is to think of it in three main parts: the bridge converter, DC link, and what we will talk about today, the inverter.
VFD: Insulated Gate Bipolar Transistor (IGBT)
WEBIGBT (insulated gate bipolar transistor) provides a high switching speed necessary for PWM VFD operation. IGBTs are capable of switching on and off several thousand times a second. A VFD IGBT can turn on in less than 400 nanoseconds and off in approximately 500 nanoseconds.
WEBThe most basic function of an IGBT is the fastest possible switching of electric currents, thus achieving the lowest possible switching losses. As the name “Insulated Gate Bipolar Transistor” reveals, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET. Therefore, the IGBT combines the advan-

Variable Frequency Drives Explained - VFD Basics IGBT inverter
WEBApr 25, 2020 · The inverter consists of a number of electronic switches known as IGBT’s. These open and close in pairs to control the flow of electricity. By controlling the path which the electricity takes and how long it flows in the different paths, we can produce AC electricity from the DC source.
Variable-frequency drive - Wikipedia
WEBA variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity.
