1. Introduction

Electric vehicles (EVs) are advancing quickly to meet decarbonization goals, driven by better batteries, faster charging, and higher-performance motors. At the heart of every EV is the traction inverter — the power electronics that converts battery DC power into the AC power needed to drive the motor. Because EVs are judged on range, performance, and cost, traction inverters are under constant pressure to become more efficient and more power-dense.

GaN DAB Converter

Thu, 21 Aug 2025 00:00:00 +0000

GaN DAB Converter designed for on-board-charging application.

This converter makes use of high frequency planar magnetics to achieve high power density in high voltage vehicles.

Active Aero Driver

This was a mini servo driver designed to power the active aero system for MY25. Unfortunately, it did not end up getting used because the mechanical setup for active aero did not end up happening :(

SiC Inverter

This is my first iteration of a SiC Inverter. It gets its own page because this version was a much less serious attempt at a working product. But it at least spun a motor!

Solid State Tesla Coil

Sat, 25 May 2024 00:00:00 +0000

How about a singing tesla coil? I designed this tesla coil to use an antenna to feedback oscillations so it can tune itself. Because of all the parasitics of tesla coils, having it self tune is pretty common. Im then using a 555 timer to modulate the signal so that the output power can be adjusted. Because of this modulation technique, the plasma patterns are super unique!

Custom Nano

Tue, 02 May 2023 00:00:00 +0000

This was my first custom microctroller board. I thought it might end up being cheaper to buy a bunch of these really cheap PCBs and solder them myself than buying a bunch of arduino Nanos. In fact it ended up being a lot more finicky than i originally thought so it looks like making your own custom Nano doesn’t make too much sense.
