Abstract :
This paper analyses small signal stability of a regulated boost converter system which supplies a permanent magnet (PM) brushless motor drive via a RLC filter. The output impedance of the boost converter is derived and the dynamics of the complete converter-filter-drive system is established based on circuit laws. The small signal stability of the system is assessed by computing the eigenvalues of the system. It is shown that the converter and drive control designs as well as filter parameters have profound influence of the system stability.
