What is SCRs?

SCRs (Silicon Controlled Rectifiers) are solid-state semiconductor devices that function as switches. They are commonly used in power control applications, such as light dimmers, motor speed control, and high-voltage DC power transmission. An SCR can block voltage in both directions, but once triggered by a gate signal, it conducts current in one direction until the current drops below a holding current.

VFDs

VFDs often utilize SCRs (or other semiconductor switches) as part of their internal circuitry for controlling the voltage and frequency supplied to an AC motor. SCRs are thus a component *within* some VFD designs.
