[PDF] Torque Ripple Reduction in Three-level SVM Based Direct Vector Modulation (DTC-SVM) schemes are proposed in order to improve the classical DTC of Induction motor. The DTC-SVM strategy as shown in Fig. 1 operates at a constant switching frequency. The inverter is controlled by the space vector modulation technique instead of voltage sector selection block as used in classical DTC. Scheme for Strengthening of Drug De-Addiction Services Department of Psychiatry and PGMIMS, Rohtak is a government run centre with both out-patient as well as in-patient facility. In their in-patient facility, they have 64 beds for psychiatry patients (32 males and 32 females) and 10 beds for de-addiction patients.
