Working as Sr. Engineer (Design) in Power Electronics and Automation Technology Centre (PRATC), in Larsen and Toubro Limited at Navi Mumbai, Maharashtra.Project : Development of LV (690V) and MV (6.6kV) drives for Induction motors.Role : 1. My role in this project is to develop control algorithms, like V/F control, sensored field oriented control ( using encoder feedback) and sensor-less field oriented control (using flux estimator, back emf calculations) 2. induction motor parameter estimation ( stator parameters, rotor parameters, mutual inductance, inertia, power loss ).3. special features for induction motor drive like DC injection braking, dead band compensation, kinetic energy buffering etc4. communication protocols e.g. Single wire protocol for optical communication for communicating two FPGA's, SCI for reat time clock, SPI for storing diagnostic, fault parameters to EEPROM etc.5. Develop electronic control cards like DSP control card, FPGA control card, SMPS card- for power supply, fiber optic interface card.Control algorithms are developed, simulated in matlab, simulink and firmware is developed in embedded C ( for Texas instruments DSP ) and VHDL (Intel FPGA).

690V Low voltage and 6.6kV medium voltage Induction motor drive development. 1. Simulate , implement and compare Sine pulse width (SPM) and Space vector modulation (SVM) techniquesfor variable frequency drives on the basis of DC bus utilization, %THD and switching losses.2. Simulation and implementation of special feature like DC injection braking, speed search, kinetic energybuffering.
