Senior Controls Engineer

Calgary, Alberta, CA

  • Lead Inverter Controls EngineerGuided the Controls group in developing advanced motor control solutions utilizing Exro's innovative open-winding motor and inverter topology for primary mover on-highway applications.
  • Architectural Innovation: Led major architectural overhauls to address safe-shutdown requirements, innovating methods that integrated and streamlined the entire derating and safety system.
  • Intellectual Property: Pioneered Exro’s first software patent, enhancing inverter reliability through novel techniques.
  • Functional Safety (FuSa) Leadership: Served as the internal FuSa advisor, introducing redundant measurement systems and rationality checks to bolster safety.
  • Toolchain Migration: Spearheaded the transition from Ansys SCADE to MATLAB/Simulink, re-architecting the control software for enhanced performance and scalability.
  • Innovative Proposals: Conceptualized and proposed a proof-of-concept control scheme for on-board charging using the Exro inverter and motor.
Oct 2022 - Aug 2024

Inverter Controls Senior Specialist

Phoenix, Arizona, US

  • Lead Engineer responsible for development of a high-voltage (800v), high-power (600kW) inverter drive system. Intended usage in class-8 heavy-duty trucks.
  • Designed a variable-frequency iFOC control in Simulink for a high-speed interior permanent magnet synchronous (IPM) motor.
  • Developed SiC MOSFET & Si IGBT junction temperature and loss model heavily used for module selection on the new inverter design.
  • Directed base-software-team (BSW) effort in setting up inverter software scheduler architecture; including loop timing, ADC & Resolver read timing, PWM generation – both continuous and discontinuous patterns.
  • Investigated multiple dyno manufactures, selected, and procured a 600+ kW, 1250Nm, 14krpm dynameter.
  • Worked with industry leader to develop a custom DC-Link capacitor and DC-bus plates to achieve <25nH of stray inductance (IGBT module + DC bus + DC-Link Cap).
Sep 2020 - Oct 2022

Senior Staff Engineer - Inverter

  • Principal Software Engineer responsible for research & development of Field Oriented Control for a low-voltage (24-48v) inverter drive system. Intended usage in forklifts and lift trucks.
  • Designed a unified FOC control method for multiple motor topologies, including AC induction (ACIM), surface permanent magnet synchronous (SPM), interior permanent magnet synchronous (IPM), and wound-rotor synchronous.
  • Designed MOSFET junction temperature prediction model to aid inverter thermal design requirements, and real-time inverter thermal limiting.
  • Designed open-loop scalar control (Volts/Hz) for automatic motor parameter identification functionality.
  • Built simulation of the inverter power-stage to provide MOSFET switch dead-time requirements, DC bus ripple rms voltage and current, DC-link capacitor sizing, and capacitor technology required.
