Answer :
Final answer:
The option not part of a variable frequency drive type starter is a buck-boost converter. VFDs normally include a rectifier, inverter, and microcontroller and control circuits.
Explanation:
The stated option not a part of a variable frequency drive (VFD) type starter is a. buck-boost converter. A variable frequency drive typically consists of a rectifier to convert AC to DC, an inverter to convert the DC back to AC at the desired frequency, and a microcontroller and control circuits to manage the operation of the drive. Buck-boost converters are not a standard feature in VFDs, as their primary function is separate from the purpose of a VFD. The main components of a VFD are intended to adjust the speed of an electric motor by varying the frequency and voltage of its power supply.
