In the previous chapter, the F28335 floating-point DSP has been selected as the evaluation board of this
project. As mentioned in Sec. 1.2, one of the objectives of this project is to make the final vector control
system exchangeable with the dSPACE system. Hence, some peripheral circuits have to be added to
achieved this objective and in addition some steps are also taken in order to enhance the system’s performance
and to protect the DSP. For example, a buffer circuit will be built to protect the DSP’s digital
input from over-voltages. In the first part of this chapter, the relative signal and interface specifications of
dSPACE are listed and according to these specifications, the signal conditioning circuits needed for DSP
are described in detail
