About Christopher R. Ellis

Hands on engineering leader with proven track record of bringing products from concept to market in fast paced environments. Keen focus on process improvement and implementing procedures that reduce development time while enhancing design efficiency and effectiveness. People-first philosophy focused on mentorship and guidance that engenders strong performance and retention. Creative problem solver that is self-motivated, adaptable, and resourceful when it comes to decision making. Specializes in power electronic designs including high power AC-DC and DC-DC switch-mode power supplies and lithium-ion battery management systems.I'm interested in applying my knowledge towards advancing DC-DC and AC-DC power electronics for Electric Vehicles and Energy Storage Devices. My passions include power electronics controls, topology optimization, root cause analysis, and battery management. Have experience working with SiCFETs and researching GANFET technologies for high power DC-DC power supplies. Designed a BMS for up to 32S and 200A of max current for Li-Ion 18650 battery packs. Would love to work with Solid State Batteries (SSB).I also enjoy learning about resonant power transfer and smart grid performance. I envision electric vehicles charging when you park in a parking lot as well as trickle charging while driving down roadways. A time where a portable device begins charging as soon as you walk into a room. A grid system that knows when a line is down which would decrease response time and repair costs. I can't wait to make these visions a reality.

  • Crellis
    Founder
    Crellis Jan 2023 - Present
    Melrose, Ma, Us
    Currently focused on educational videos and content on Youtube.Shattering the notion that process stifles innovation. Crellis’ mission is to bring more efficient and effective processes to startups so they can focus on developing innovations.Process improvements are about saving the engineers time and company money. When people think process engineering they imagine large cooperations with year long development and review cycles. Engineers often feel the majority of their time is spent writing a report or creating auxiliary documentary for cross functional reviews. Distracting from the core technology they are developing.For startups, process improvement could be as simple as reviewer roles or design validation. It’s important to fit the process to the company size and industry.
