Design theory for revision 3 of the 5 V to 170 V DC-DC Boost converter
The prototype of the converter seemed to be working fine, but it could be improved. In this article, I will design the converter from scratch using equations from Under the Hood of a DC/DC Boost Converter and the datasheet of the UCC3803 to account for component values and show my understanding. Before we get started,…

My journey of creating a 5 V to 170 V DC-DC Boost converter
For a Nixie clock I was designing, I needed a compact but functional and stable 170 V supply for upwards of 18 mA. The only available source on our board is 5 V, as we wanted this product to work on any USB supply that supported our current draw on 5 V to eliminate the…

Creating a Bode plotter with an oscilloscope, function generator and Python
At work, I recently used a bode plotter to characterize the gain and phase margins of a high-performance buck converter. I found this device to be fascinating and wanted one for myself at home. I could not think of a reason why, but then again, why not? I thought of combining LXI on my oscilloscope…
