<p>A Tesla coil is a resonant transformer circuit that generates very high voltages which are made to arc through the air. Recently, a solid state Tesla coil was produced according to developing the semiconductor. In addition, the solid state Tesla coil makes sound by the air discharge. Hence, the sound is used as musical devices. In the past, the musical solid state Tesla coils are generated by PWM (Pulse Width Modulation) method. 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 not PWM method but PRF (Pulse Repetition Frequency) method. As the result, the proposed musical solid state Tesla coil provides good sound.</p>
