Specification

Description:FIELD OF THE INVENTION
This invention relates to electrical engineering and high-voltage technology, specifically a new design for a solid-state Tesla coil (SSTC). The invention replaces traditional spark-gap mechanisms with a solid-state switch, improving efficiency, safety, and control in generating high-frequency, high-voltage arcs. The Tesla coil's applications range from scientific research and educational demonstrations to practical uses in high-voltage systems.
BACKGROUND OF THE INVENTION
Traditional Tesla coils, known for their ability to produce high-voltage, high-frequency electrical discharges, utilize spark-gap mechanisms to excite the primary winding, generating a high voltage at the secondary winding. However, spark-gap systems are prone to inefficiencies, reduced control, and safety hazards due to the high current discharge. This invention addresses these issues by introducing a solid-state switch, specifically an NPN transistor, as a replacement for the traditional spark-gap. The transistor allows for frequent, controlled switching in the primary winding, resulting in high-voltage arcs on the secondary winding within a safer and more efficient system. The improved design produces voltages ranging from 5,000 to 36,000 volts at very low current, making it safer for demonstration and research purposes without compromising performance.

The solid-state Tesla coil (SSTC) introduced here operates as a resonant transformer with high-frequency output, employing a solid-state switch in place of the traditional spark-gap mechanism. This Tesla coil design consists of a primary winding connected to a solid-state NPN transistor that serves as a switch to excite the primary circuit. The NPN transistor's rapid switching generates oscillations that resonate through the primary winding, inducing a high-voltage output in the secondary winding.
The SSTC operates at an input voltage between 25V and 120V, allowing for flexibility in power sources and accommodating varying levels of high-voltage output. With approximately 4-5 turns in the primary winding and around 1,500 turns in the secondary winding, the SSTC achieves efficient voltage transformation and high-frequency output. The secondary coil's high voltage can reach up to 36,000V in direct current (DC) at very low current levels, making it safer for demonstration purposes as the current is insufficient to cause harm. However, the high-frequency radiation emitted during operation requires caution, as it can cause harm over prolonged exposure.
The SSTC's secondary winding is connected in such a way that it excites surrounding air molecules to form plasma, which is visible as arcs emanating from the coil's terminal. This feature is particularly useful in educational displays and research applications, where observing high-voltage plasma arcs aids in understanding electromagnetic principles. Furthermore, the SSTC is scalable and can be adapted for industrial applications by adjusting the number of windings and the input voltage, making it versatile for diverse high-voltage requirements.
Compared to traditional Tesla coils, this design's solid-state switch offers greater control over the frequency and intensity of voltage output, reducing safety risks and improving energy efficiency. The SSTC's simplified design minimizes maintenance requirements and enhances durability, positioning it as an innovative solution in the field of high-voltage systems for educational, research, and industrial applications.
