Built with a modern half-bridge integrated design, this Tesla coil delivers stable performance, reduced heat generation, and efficient operation, making it ideal for both educational and enthusiast use.

Capable of generating plasma arcs up to 10 cm in length, this compact yet powerful unit utilizes a frequency-tracking system with feedback from the secondary coil to maintain optimal resonance. The secondary coil is precisely wound using pure copper enameled wire and coated with insulating paint for enhanced durability and performance. The flat PCB primary coil design not only improves efficiency but also gives the device a clean and modern appearance.

Equipped with an onboard pulse width and frequency adjustment potentiometer, users can fine-tune the discharge frequency (up to approximately 60Hz) and pulse duration (up to 1ms), allowing for customizable arc effects and operation modes. The unit also supports square wave music playback via a 3.5 mm audio input, transforming electrical discharge into sound for a unique audiovisual experience.

This upgraded model features improved integration, including a built-in rectifier module that allows direct AC power input, eliminating the need for external components. Additionally, the device includes a virtual grounding system, removing the requirement for separate grounding, which simplifies setup and operation.

With its compact desktop size and professional-grade performance, this Tesla coil is perfect for laboratories, classrooms, exhibitions, and serious hobbyists looking to explore the principles of high-voltage electricity and Nikola Tesla’s innovations.
