  Electrical Engineer

  While at this company, I served as an Electrical Engineer specializing in Power Electronics circuits, particularly on Motor Drives. My primary responsibility was to lead the design of a 400VAC inverter for a 7.5kW Elevator motor driver, using DSP TMS320F28069M and INSTASPIN-Motion technology to achieve sensor-less Field Oriented Control. Other Projects: - Test, debug, and deliver technical insights on the Load and Phase Control Board for Elevator Motor Safety.- Design and implement an ISP programmer for ATMEGA32 and ATMEGA64 to expedite programming process- Participated in the development and implementation of UPS systems for various power stages (1kW, 2kW, 3kW, 5kW, 10kW), including the implementation of a battery charger and low-frequency transformer.-Prepared technical documents relating to design procedures and product specifications for marketing and development purposes Show less
