Near Zero-Ripple Switched Reluctance drives

This paper introduces a Zero First-order (or Fundamental-harmonic) Ripple (ZFR) drive topology for Switched Reluctance Machines (SRM). The proposed drive topology utilizes ripple canceling techniques to eliminate first order ripples on SRM phase currents. This paper will first introduce the proposed ZFR drive topology. Then a Least-Quadratic Regulator (LQR) controller is proposed to utilize the ZFR topology in an optimal fashion. Experimental results are provided to demonstrate the effectiveness of the proposed drive technique.
