Adjustable Power Supply v18.08
To Do/In Progress
Code for Arduino PWM control and voltage sensing
Design buck/boost converter circuit/module
Volt-second balance on the inductor means that the average voltage across it is zero
Discontinuous mode is when current through the output inductor is zero for part of the switching cycle
Investigate ways to increase frequency of AC input
Figure out ways to salvage or build transformers
Design
