A Tesla coil is a resonant transformer circuit that generates very high voltages that are made to arc through the air. Recently, a solid‐state Tesla coil was produced using semiconductor switching devices. In addition, the solid‐state Tesla coil makes sound by air discharge, and the sound is used in musical devices. In the past, pulse width modulation (PWM) method was used to produce musical solid‐state Tesla coils. However, it is difficult to use the high‐pitch sound and the tone color. This paper investigates the musical solid‐state Tesla coil by using pulse repetition frequency (PRF) method. The proposed musical solid‐state Tesla coil using PRF method provides good sound.
