Development of a Controller for an Interior type Permanent-Magnet Synchronous Motor

2019, dr_chandana

Abstract:

Interior type Permanent-Magnet Synchronous Motors (IPMSMs) are getting popular to use in many motion control applications. High efficiency and their compact design are the main reasons to attract them for motion control applications. Those applications vary in a wide spectrum from domestic applications to advanced industrial applications. Recently, they have been applied successfully in Hybrid and Electric Vehicles to operate both in motor and generator mode. The objective of this project is to develop a controller for an IPMSM so that it can control the speed and the torque precisely. Voltage Source Inverter (VSI) is used as the power electronic converter to supply the suitable voltage to the IPMSM. All control functions should be implemented in a micro-controller incorporating suitable sensors. A prototype IPMSM drive system will be developed in the laboratory incorporating a VSI, microcontroller and suitable sensors.

Integrated Power Flow Controller for a Grid Connected Three -Phase Three- Level Multilevel Inverter Embedded with an Energy Storage in an AC Microgrid

dr_chandana, 2019

Abstract:

In order to suppress the intermittency of renewable sources integrated into an AC microgrid, the current trend is to embed an energy storage with innovative power flow controller with the intermittent renewable source. In this context, multilevel inverters (MLI) are getting increasing popularity rather than conventional two-level inverters as the power electronic interface due to many merits associated with MLIs. This work designs and implements the control system of the 1 kW grid integrated energy storage with a three-phase three-level multilevel inverter for controllable power injection using current mode control. The proposed system consists of a three-phase three-level MLI connected to a battery pack through a DC-DC converter and injects controllable active and reactive power to the grid. All control functions wiil be implemented in a micro-controller incorporating suitable sensors. A prototype power flow controller will be developed in the laboratory incorporating the MLI, microcontroller and suitable sensors.
