A collection of projects before my PhD
Before my phd, I have worked hard my way through in both industry and academia. This blog collects most major prototypes I have developed or led with a brief introduction. I am not actively working on them anymore. However, in case you might be interested in any of them, I still have their design documents, and am ready to give them away for free -- just send me an email.
Totem-Pole Power Factor Correction Rectifier
A 3 kW totem-pole pfc rectifier.
This is a work of my one-year part-time internship with a local company in Xi’an. Not only just one prototype, I was also hired to give lectures of power electronics to their technicians – I would have felt used, but luckily I actually liked teaching.
Compact GaN Rectifier
A 150 W full-GaN rectifier.
This is the work for a competition funded by GaN Systems (now a part of Infineon) in China. We worked really hard but wasn’t eventually strong enough to compete with other stong teams. It was a great experience – I still remember how it smells when a GaN transistor burns.
Stackable LLC DC-DC Converter
A stackable isolated dc-dc converter.
I was so bored when I already submitted my thesis and waiting for my visa to fly to USA. And I suddely decided to do something different about LLC, a topic which I don’t actually know much about. And LLC was everywhere. Eventually I figured out a way to connect different boards with one connector while parallel their output (thanks to gorgeous Taobao, that might be the only thing I miss here in America). There isn’t actually any outcome from this prototype, except some fun for myself.
Super-conductor mag-lev car
A maglev rail car.
I was leading a tech-camp in 2016 summer on superconductor technologies. This is one of our major demonstrations – a rail car with a superconductor base floating and racing on a track made with 20,000 magnets. The base is filled with liquid nitrogen to keep itself cool. The propeller is a remotely controlled electric fan.
