High Efficiency PMSM Inverter for EV Application | https://github.com/liongma/Inverter Co-Optimization of a 3-Phase, 50 kW, 600 V Power-Dense SiC VSI for PMSM Drive Liong Ma Massachusetts Institute of Technology liongma@mit.edu 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 designed for on-board-charging application. This converter makes use of high frequency planar magnetics to achieve high power density in high voltage vehicles.

This is a scanning tunneling microscope i made! If it looks janky, thats because it absolutely is. In fact, most times in the day, the thermal expansion of the device causes the SNR to be extremely low causing the device to be unusable. But for a couple hours of the day (for me around 4PM), the temperature peaks and theres a brief 20 minute window for some mesmerizing photos to be made.

Overview This project’s objective is to design and prototype an affordable electric racecar to demonstrate the potential for EVs as an economically viable and environmentally sustainable transportation solution. Objective The main objective is to create an electric vehicle within 6 months with a budget of $15,000 or less, capable of reliable road performance while minimizing the use of premade or off-the-shelf components. Scope This project involves the design, engineering, and fabrication of the following systems: Mechanical Chassis, Suspension Assembly, Traction battery, Electric power train, Auxiliary Battery, Auxiliary System, Secondary System, Proximity System, Thermal Regulation, User Interface, Energy Management, and Communication Systems. ...

This thing is so cool. I bought a diffraction grating and thought about how cool it would be if I could make something to decode the signals. I have it fed into a raspberry pi with a screen, that calibrates from LEDs and then uses that to find peaks at different optical frequencies. This is then used to find an element in its database to figure out what exactly is producing that light. Then, I used one of my many plasma generators to test how well it works. ...

This is the traction system for the AE boat. It uses a bunch of quickly switching FETs to drive the motor, and uses two relays to switch the direciton the boat is moving, pretty intuitive stuff!
