About

I'm Kristian Skorpen. I work as a power-electronics engineer at Pixii, a Norwegian battery-energy-storage manufacturer. My day job is designing and tuning controllers for grid-connected inverters and DC/DC converters that go into commercial and utility-scale BESS.

Background

• MSc Electrical Engineering, NTNU (Trondheim) — focus on power electronics and control.
• Currently studying Economics part-time at the University of Oslo (UiO) — interested in how power markets and grid services price BESS dispatch.
• Day-to-day: ACMC tuning, dq-frame inverter control, PLLs, dead-beat control, DC-link sizing, EMI filter design.

Why this site

Most teaching material I find online is either too academic (stops at the transfer function) or too marketing (a 30-minute YouTube video that doesn't show the code). I publish what I'd want a new engineer joining my team to read on day one: a derivation, a Simulink model that runs, and a notebook that reproduces every plot.

The courses are paid because writing them takes weeks. The simulation models are free because they're a byproduct of work I do anyway, and I want them used.

What I'm working on next

• Single-Phase Totem-Pole PFC course — launching mid-2026.
• Blog — companion articles to YouTube videos + posts on BESS and power-market topics, starting 2026.
• Three-phase course — possibly 2026/2027, depends on demand.
