How to Design 24VAC to DC Power Supply for HVAC Applications Part 2

In the video we look at how to design a 24VAC power supply for industrial and HVAC applications. The supply will be flexible enough to handle DC voltage inputs. The power supply will employ a DC to DC buck converter, half wave rectifier, input protection against over voltage, and output noise reduction circuit features. In part 2 we look at the PCB design, the finished product, and capture some test data to see how it is working.

Ultimate Battery Circuit Design Part 2

In this video series we build the ultimate battery circuit that can handle various battery chemistry's, charge batteries, perform load sharing during charging, handle input voltage levels that are higher or lower than the output, and more. In part 2 we will look at the PCB layout with a focus on the buck boost DC to DC Converter and look at the BOM.
