PEMF FLASH technology
It is important to understand that both technologies are based on the same principle to charge energy into a capacitor but completely different how these energies are discharged into a PEMF coil.
FLASH technology is the latest state-of-the-art because it makes use of electronic solid state technology while obsolete Spark systems use outdated technology with many disadvantages compared to FLASH technology.
Curatron FLASH impulse technology is basically similar to technology used for flash photography, however much more advanced because of the enormous amount of energy charged in a high voltage capacitor system followed by release of this energy into a PEMF coil.
Electronic flashes are a simple and inexpensive solution to generate a short burst of bright light when releasing the shutter of a photo camera. A basic camera flash system used in a point-and-shoot camera has three major parts.
A battery power supply
A circuit with electronic components
A gas discharge tube producing the flash
A discharge tube is a tube filled with xenon gas with electrodes and a trigger plate.
A capacitor is a kind of accumulator able to hold electron energy charges for a limited time.
When switching on the flash function of a camera the electronic circuit inside the camera transforms the battery’s low voltage into a high voltage, which slowly charges a capacitor to a few hundred volts. Usually a high-pitch whine is heard caused by this process during the charging of the capacitor.
The high voltage capacitor is connected to the electrodes on the flash tube at all times, but unless the xenon gas is ionized, the tube cannot conduct the current and the capacitor will only discharge when the trigger plate is activated.
Pressing the camera shutter closes an electronic switch to the trigger plate, releasing the stored energy from the high voltage capacitor suddenly into the discharge tube, ionizing the xenon gas inside and causing the atoms to emit the well-known high intensity light flash.
In a very similar way works the PEMF Curatron FLASH impulse devices. A very high voltage capacitor is charged super fast between each pulse. Then within the fraction of a second the capacitor is discharged, under computer control, by a very high voltage & high current solid state semiconductor switch into the PEMF coil.
This sudden discharge of the very high voltage capacitor causes a huge current to run in a fraction of a second through the coil creating a very high intensity electromagnetic impulse.
The lower the pulsing frequency, the higher the PEMF intensity will be, because the time it takes to charge the capacitor becomes longer between each pulse. The more time for charging the capacitor to a higher voltage between each pulse the higher the amount of energy stored in the capacitor and hence the more powerful the pulsing electromagnetic field will be when this energy is suddenly released into the coil.
Some manufacturers of similar high intensity impulse PEMF devices still use obsolete spark gap technology which has numerous technical problems and more about this on the Spark page.
