Hey everyone,
Just an introduction - My name is Tony and I am new to posting on the forums. I am an electrical engineering undergrad and I have been following much of what goes on in the forum, youtube, and the energy from the vacuum series. During my fall semester I discovered Bedini’s SSG circuit and later that semester built my first Bedini motor. Since then I have been experimenting with various aspects of the circuit and soon moved to solid state variations of the circuit. I would just like to post some results from my variation of a solid state circuit and also relay switching circuit to see if anyone has had result like mine or would like to replicate it to help further the development of a transient spike battery charger.
My first experiments delt with a TIP42 PNP transistor followed up by a string of 2n4005 diodes to stop the Bemf. I then rectified the coil by using a full wave bridge rectifier which is placed parallel to the coil. Then for safety I placed a 120 VAC neon across the positive and negative terminals and charged a 400v 220uF cap. (I posted a picture of the basic circuit design) Using a 555 chip I was able to control the frequency and duty cycle. I used about 200 Hz with around 33% duty cycle.
The cap charged very quickly so I started measuring the joules to see how much energy was being captured.
The overall wattage of the system turned out to be about 1.25 W and it took about 8 second to charge the cap to 125v.
Using (.5 * F * v^2)/(1.25W * 8 seconds) = (.5*.00022 F * 125^2 v)/(1.25 W * 8 seconds) = 0.171875 or a COP of .172 … Clearly under unity. The max I could get the voltage to go was around 135V, so only about a 135V transient spike.
I then wanted to try mechanical switching to get perfect square waves so I bought a small 24v/1A SPDT relay and replaced the transistor with the relay. With only about 30 Hz on the output of the 555 chip I was able to charge a 500 volt 40uF cap all the way to 500 volts! I then put my two 500 volt caps in series and was able to achieve about 600 volts before my multimeter stopped reading voltage!! Therefore the transient spikes I was observing were easily achieving > 600 volts!!
Next I threw a 9 volt battery(non rechargeable) across the bridge terminals and amazingly it recharged in 15 mins without any heat and less draw on system changing the wattage from 1.25 watts to .75W. I threw all the batteries I could find (all dry cell) onto the charger and amazingly I had the same result every time, less amp draw (after frequency and duty cycle tweeking because the impedance of each battery was different), and a full charge on a cold battery.
The most amazing find was to my Li-ion 1400 mAh 3.7v cell phone battery. My phone was desperate for a charge so I though, hey why not. I took the battery out of the phone and put it into the circuit. To my amazement after only 30 mins, and at only about 1 watt of input power my phones battery went from 3.5 volts to 4.2 volts (a full charge) and was room temperature if not a little colder. My normal charger takes about 2 hours to fully charge the phone and it is boiling hot afterwords. But there was a downside to this, upon putting the battery back into the phone, it informed me that the battery I was using was a non supported battery, which means I’m going to Verizon tomorrow and complaining
Thank you for taking your time to read this post, once again I’m new to this so please don’t yell at me if I did anything wrong in the post
.I plan on taking pictures of the circuit if not a video to further explain. Anybody wishing to replicate please do so and post your results in this thread. Once again thanks a lot and in you need any more information about the circuit I will be pleased to share.
