In this latest educational video, I like to demonstrate the performance of power mosfet in the pull – pull configuration. While I was able to show successful half bridge configuration many years ago in England on YouTube, the performance could not be increased above a certain value. The classic Half Bridge design has flaws from an impedance and performance point
I like to present the educational video about DC power sources and the ripple factor. Here I go into more details what power supply to use and the issue of ripple for your application. While it is easy to see that just rectifying mains AC should be the smartest way, it is in fact not. Switched mode power supplies are
I have produced a new video for the educational sector under research. Now I compare the Class C amplifier we all use with the Half bridge of conventional design and my proposed solution of a pull – pull Half Bridge. While we all have our fair share of obstacles to get a half Bridge working my proposal will feel like
As promised, I give you the educational video in courses and electronic design. This video is available to Full and Basic members only. While I did spend years investigating the different amplifier types I only learned that instead of simplifying everything is becoming more and more complicated. Many of you asked me for amplification solutions for scalar wave systems. It
I like to announce the availability of the next video in the NG coil design series. Here I test two Caduceus coils and their output performance. The coil requested for the build will be part of it. I also apply various optimization options available. Impedance matching, magnetic core influence, and asynchronous output coil configuration. The video is available under the NG coil Design page
I am happy to announce the release of the 4th part of the NG Coil design. Here I look at the TEP (Time Energy Pump) principle. You will see parametric behaviour of coils wound in opposite direction. A load of 1 KOhm is used for testing via a bridge rectifier to allow clear power efficiency comparison. I have observed this
I happy to announce the release of the third part of the next Generation coil design. In this video I will look at the overall performance of coil systems including the power delivery from the signal generator. While the overall performance of the coil from input to output is COP > 1. looking at how much we have to pump
I like to announce that the performance chart for all tested cores are now available. The link is on the page of the last testede core. The direct link for Gold members is here
I have released the next video of the test series of ferrite cores. This is the M-088 nanoper core from Magnetec. It is a filter core with extraordinary performance values at higher power values. It shows in self triggered mode like the Joule Thief or the LED driver circuit very low frequency response based on the high permeability of the
I have released the next video of my testing series of the anomalies of ferrite cores. I test the N30 core which has outstanding performance levels where all loads perform very well. The video is available under Movies and the direct link for Gold members is here TheOldScientist
