Tesla Coil Software
Kaizer SSTC II Kaizer Power Electronics. Introduction. This is a modified version of the first SSTC I built, the Kaizer SSTC I. It uses the same secondary, topload and driver board. New things is a full bridge of IRFP4. MOSFETs, audio modulation, shielded drivers and a new casing. Safety. WARNING Working with electricity is dangerous, all information found on my site is for educational purpose and I accept no responsibility for others actions using the information found on this site. Read this document about safety http www. Considerations. In the quest for longer sparks I decided to use a full bridge to take advantage of the full voltage on the bridge. The MOSFETs will be mounted on top of a heat sink so its easy to change them by only removing the secondary platform and solder them off. The drivers will be shielded in order to avoid the EM field generated by the Tesla coil itself to inject noise into the drivers. Specifications. Bridge. IRFP4. MOSFETs in a full bridge configuration. Bridge supply. 0 2. VAC from a variac, 8 A rectifier bridge and 1.

Within the timeline of radio, many people. Tuning a tesla coil can be done in various ways depending on what equipment you have access to. The most accurate is with an oscilloscope and signal generator. Article by Bill Morgan about scientist Tom Bearden and the new scalar weapons called Tesla howitzers. Scrollable Dock.

X are MOSFET driver ICs, one non inverted output and the other inverted, in order to get a push pull drive of the gate drive transformer. A gate driver IC can deliver the high peak currents needed to drive MOSFETs efficiently. The 7. 4HC1. 4 is a inverting hex schmitt trigger, it is used to get a proper solid 0 5. V square wave signal from signals that are not perfectly square, the antenna feedback can vary a lot in waveform and amplitude, the 7. HC1. 4 converts this to a clean drive signal for the MOSFET drivers. All unused input pins of a 7. HC1. 4 has to be tied to ground, floating inputs and a noisy environment is a recipe for trouble. The noise can couple between the gates internally and make the whole IC not work properly. The music modulator works by amplifying the audio signal in the LM7. BC5. 47 transistors. The 5. 55 timer ensures that the signal length of the generated square wave is much shorter than the audio signal, in order to not have too long on time and thus damage the MOSFETs IGBTs from over current. Construction. 15th March 2. I took apart a 1. LCD monitor and a 2. CRT monitor, from these respective computer parts I salvaged a good piece of acrylic from the LCD monitor and a fairly sized heat sink from the CRT. I cut the acrylic in half for a 2 level platform and the heat sink was cut in 4, its necessary to isolate the MOSFETs from each other as their housing is also a conductor. March 2. 00. 9Driver electronics and audio modulator are installed under a metal casing from the CRT monitor to shield it from the heavy EM field surrounding the Tesla coil, this is to avoid problems with the driver being interrupted by its own EM field. The bridge is made out of four IRFP4. MOSFETs, four MUR1. R resistors. The power supply is a 8 A rectifier bridge with a BHC 1. F4. 50 V smoothing capacitor, a 2. K 7. W bleeder resistor is added in the final build. The audio in jack was later removed due to it making a short through its metal housing to the ground rail, I had overlooked that the audio in negative was not common with the ground rail, but there is a capacitor inbetween. The secondary is held in place by a crate for ventilation on houses, its an easy and quick way of taking the coil apart for transport or storage, and it holds the secondary firm and tight. A acrylic tube is added to support the antenna, in this way it is possible to adjust the coupling of the antenna to the secondary simply by pulling the wire. The new shielding of the audio in signal is made from a piece of shielding from a industrial cable pulled over it and grounded. The secondary with terminations. The complete coil looks, except maybe the electrical tape used to hold the topload together. Sparks. Interrupted mode. At 2. 50 VAC input voltage, 3. VDC on the bridge, it was possible to reach 4. More pictures of sparks in interrupted mode, it is running at about 4 5 BPS. May 2. 00. 9Continues Wave mode. At 2. 00 VAC input voltage, 2. VDC on the bridge and a power consumption around 1. A, peaking at 2. 0 A, the coil was drawing somewhere in between 2. Watt. This resulted in very hot, thick white arcs punishing the dead i. Pod shuffle which remarkably left the player relatively unharmed considered what had just taken place. These flame like sparks are 2. August 2. 00. 9I constructed a new topload from two cheap aluminium frying pans from Ikea. With handles cut off and screw from it grinded away it had a smooth surface and was fixed with a long screw through both of them. September 2. 00. 9During a run of CW at full input voltage, the full bridge blew apart completely, with a loud bang. Audio modulation. I use a audio modulator made by the user Reaching Martin Ebbefeld from 4hv. For sound input I use a cheap childrens keyboard from a toy store, its far from perfect for the job, especially because its waveform is highly distorted and its not clean tones but seems to involve a lot of modulation inside it to simulate different instruments. But its cheap and expendable. Atioglxx.Dll Jedi Academy more. Watch the film and look at the schematics for more about the audio modulation. Conclusion. Upgrading the SSTC I with a full bridge was a absolute must. It is small changes compared to the better performance and the driver have no problems at all driving four MOSFETs instead of just two. Getting sparks at 4. Enjoy the demonstration. Demonstration. Demonstration of different modes. New topload, running in interrupted mode. New topload, running in CW mode.
