A Complete Guide to Inverters/Variable Frequency
In this article, we will take a look at what an inverter is, where inverters are used, why we use them, and finally some of the most frequently asked questions about inverters/VFDs.
VFD: Variable Voltage Inverter (VVI)
The VFD variable voltage inverter (VVI), also named Voltage Source Inverter (VSI), uses an SCR converter bridge to convert the incoming AC voltage into DC. The SCRs provide a means of
Variable-frequency drive
In variable- torque applications suited for Volts-per-Hertz (V/Hz) drive control, AC motor characteristics require that the voltage magnitude of the inverter's output to the motor be
