💡 Comidox 15KV Boost High Voltage Generator & Transformer Inverter Coil Module Disassembled Parts - DIY Kit (2 Sets with PCB Board) Review

This kit is made for the booster coil and has a professional circuit diagram for the convenience of electronics enthusiasts.1 set of list:PCB Board/120 ohm resistance/UF4007 ultra-fast recovery diode/N20 transistor/Heat sink/M3 * 6 screws/Boat switch/Pin header (3-8 Pin random). Uses: Chinese-language general experiments, electronic instruments, negative ion generators, scientific small production, etc. This circuit works with a stable high-frequency arc, which is extremely high in temperature and can easily ignite combustibles. Therefore, it is called a plasma lighter. Transformer structure: The transformer has two windings in the primary, one set of thick copper wire is the main winding, one set of thin copper wire is the feedback winding, and the secondary output is high voltage. In the transformer, two thick and thin copper wires are wound together, which are the main winding tail and the feedback winding head, respectively, connected to the positive pole of the power supply. Before welding the transformer, it is necessary to scrape off the welded portion of the coating and the covered wire tip with a blade and then solder. After successful production, the transformer must be potted with epoxy or insulating wax for long-term use. The maximum output of the transformer is designed to be 15KV, and the maximum output must not exceed 15KV, which is 1.5cm arc. The kit has an input voltage of 3.7V. That is, the voltage of the 18650 battery, if you need to increase the input voltage (maximum increase to 12V), you need to increase the resistance of the feedback resistor (package resistance is 120 ohms), otherwise the triode is easy to burn out. The feedback resistance is increased to approximately 150 Ω to 1.5 K Ω. Resistance should be adjusted from large to small. It should not be too small.
