I am a passionate Senior Power Electronics engineer with 5+ years of experience in the industry. My working area includes the design and control of power electronics converters (AC/DC, DC/DC, DC/AC), electromagnetic simulation for magnetic design, circuit simulation for power converter with applications in on-board chargers for EVs, inductive power transfer for low-power and high-power applications. I am fully committed to the team I am working on where support is mostly needed. I graduated with a Ph.D. degree in Power Electronics from the University of Texas at Dallas in June 2022.
My focuses during Ph.D. program are Power Electronics and Motor Drives, including: - Thermal management for heatsink and Interior Permanent Magnet (IPM) machines using Ansys Maxwell, Ansys Mechanical and Ansys Fluent. - Inductive power transfer for Electric vehicle (EV) battery charging application at frequency of 85kHz. - Isolated Gate Driver Power Supply for medium-voltage converters based on high-frequency wireless power transmission at frequency of 4MHz. - Analyze common-mode current performance of gate drivers.
- Investigating different topologies for isolated power supply of gate drivers that satisfy low profile, low cost, and high efficiency, specifically focus on these below topologies: Push-pulse, full-bridge, and LLC resonant topology. - Designing a low-cost biasing circuit for driving SiC Mosfets using shunt regulator TL431. - Analyzing crosstalk phenomena, and suggesting solutions to reduce crosstalk and increase the reliability of SiC Mosfets. - Modelling turn-on and turn-off transients of MOSFETs: Writing differential equations to describe ringing of gate-source voltage, drain voltage during turn-on and turn-off transients. Using MATLAB to find solutions.
Automate FEM simulation of Wireless Chargers using COMSOL: - Writing a script in Matlab to automate the import of CAD files into COMSOL and set up simulations (materials, boundary, etc). Thus, reducing 95% modeling time. - Created a graphic user interface (GUI) app using MATLAB.
Main duties: 1. Design power electronics components for an inductive power transfer (IPT) system like Amplifiers and Inverters. 2. Simulate IPT system in 3D maxwell simulator. 3. Building up an Automation platform to create IPT systems automatically in a 3D Maxwell using Visual Studio, which reduces the 3D model drawing time by more than 95%. 4. Circuit design using circuit simulators like Multisim, Psim, Simplorer. 5. Proficiency in Ansys (Maxwell, HFSS, Simplorer), COMSOL, CST, and ADS. 6. Programming languages: Matlab, Python
