    Standalone single stage PV fed reduced switch inverter based independent control of two PMSM drive
    (Institute of Electrical and Electronics Engineers Inc., 2018) Karthikeyan, A.; Koothu Kesavan, K.K.; Abhilash Krishna, D.G.; Nagamani, C.
    This paper proposes a standalone singe stage PV fed air cooler which consists of two motors (fan blower and water pump). The proposed system comprises of PV source, reduced switch inverter and two PMSM drive. The proposed system aims at reducing the switching losses and overall cost by using reduced switch inverter. The reduced switch inverter uses only eight switches whereas the conventional VSI utilizes twelve switches. In the proposed scheme, blower and pump are independently controlled using field oriented control scheme where speed reference is obtained using Perturb and Observe (PO) technique. Simulation studies for the proposed PV fed two 400 W PMSM driven blower and pump is performed using MATLAB platform and respective results are presented to show the efficacy of the system. © 2018 IEEE.

    Single stage PV fed reduced inverter based PMSM for standalone water pumping application
    (Institute of Electrical and Electronics Engineers Inc., 2018) Karthikeyan, A.; Koothu Kesavan, K.K.; Varsha, S.; Venkatesa Perumal, B.; Mishra, S.
    This paper proposes a standalone PV fed PMSM drive for water pumping. The proposed system aims at reducing the switching losses and overall cost by using reduced switch inverter. The proposed system comprises of a PMSM drive, fed by PV source through an inverter employing reduced number of switches. The inverter uses only four switches whereas the conventional VSI utilizes six switches. Field oriented control scheme is employed to control the PMSM drive. Perturb and Observe (PO) MPPT technique is used to generate a speed reference to PMSM drive. Simulation studies for the proposed PV fed 400 W PMSM driven water pumping system are performed using MATLAB platform and respective results are presented to show the efficacy of the system. © 2018 IEEE.

    Hybrid Control of Single-Phase to Three-Phase Reduced Switch Converter for PMSM Drive
    (Institute of Electrical and Electronics Engineers Inc., 2018) Karthikeyan, A.; Varsha, S.; Koothu Kesavan, K.K.
    This paper proposes hybrid control for single phase to three phase reduced switch converter based PMSM drive that can be used in remote locations where only single phase grid is available. PI, hybrid (hysteresis+ PI) controllers are employed for controlling the input and output sides of the converter respectively. This configuration for PMSM drive has a shared leg between output and input sides. The input side PI controller synchronizes input grid current with the grid voltage to maintain unity power factor during load and speed variations. This configuration has unity input power factor and allows bidirectional power flow. The proposed system is modeled for 400W motor in MATLAB/SIMULINK environment and the simulation results are presented. © 2018 IEEE.
