Variable Speed Drive VSD must be grounded in accordance with the 2017 NEC Paragraph 250118. The below block diagram illustration depicts a typical three-phase AC variable speed drive system. Ground wires must be copper only and sized per the NEC.

The basic function of a variable speed drive VSD is to control the flow of energy from the mains to the process. The function of each block is as follows. The four blocks or sections of a VFD are Rectifier DC busfilter Inverter.

Refer to Table 250122. Generally a VFD is made of four blocks or sections where each section has its own function. Energy savings using variable speed drive by modulating fan speed has been estimated.

Electrical adjustable speed drives typically consist of three principle elements as outlined below and as shown by the system block diagram in Figure 1. Most VFDs operate by first changing the AC voltage into DC and then DC is changed back to AC at the desired frequency. Variable speed drives sit between the electrical supply and the motor.

The block diagram of a typical VFD can be divided into three major sections. The block diagram of an electric drive is shown below and the load in the diagram signifies different kinds of equipment which can be built with an electric motor such as washing.
