AWD is all the wheels having power at some time, 4WD is a switch to make all four wheels have power,I should say a switch,or lever,and maybe hubs that need turned to lock in.4WD vehicles will run in two wheel drive.They might drive on either front or back wheels until locked in. FWD is just front wheel drive only.
A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable-speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.he VFD controller is a solid-state power electronics conversion system consisting of three distinct sub-systems: a rectifier bridge converter, a direct current (DC) link, and an inverter. Voltage-source inverter (VSI) drives (see 'Generic topologies' sub-section below) are by far the most common type of drives.
