This paper presents a theoretical analysis of the criteria which govern the stability of a current source rectifier drive, for a switched reluctance machine or actuator. A small signal stability analytical model, employing a state-space averaging technique, is established and verified by a comparison with a time-domain numerical simulation study. In order to fulfil the power quality requirements of...
The functional models derived in previous work for stability analysis of electric power systems for “more electric” vehicular technologies is validated by time domain simulations of a test system using both the derived functional models and behavioral models in which details of the converter switching process are fully represented. The analytically derived functional model is employed to perform small-signal...
This paper investigates the influence of control bandwidth on stability of permanent magnet brushless motor drives which are fed from a DC power source via a passive LRC filter. It is shown that if the current and speed control bandwidths of the drive is sufficiently high, the drive behaves like a constant power load, and the system stability margin decreases with the increase in output power. When...
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...
This paper analyses the stability of matrix converter-fed permanent magnet brushless AC motor drive systems. By employing state-space averaging technique, the governing equations for the dynamics of the drive system are derived. The stability of the system is analyzed by computing the eigenvalues of the Jacobian matrix of the linearized state-space equation under a given operating condition. It is...
This paper presents a comprehensive assessment of small-signal stability for a ldquomore-electricrdquo aircraft power system consisting of a synchronous variable-frequency generator which supplies several power electronic controlled loads via an 18-pulse autotransformer rectifier unit (ATRU) for AC-DC conversion. Functional models for key power system components and loads are derived. Numerical tools...
