Previously I shared the quality Tesla Coil Circuits in Solid State Tesla Coil. This tesla coil drive circuit is controlled by tesla bobini according to a slightly different sound signal. TL494 IR2110 IGBT Tesla coil control doing a kind of tesla vu-meter or vu-tesla control can be controlled by motorda instead of high power PWM cycle tesla coil …
The first tesla coil driver circuit used old tube TV or monitor EHT high voltage transformer. EHT transformer is already used in many high voltage spark project. There is ready high voltage winding. In the first version IR2110 unused TL494 output is powered by BD139, BD140 transistors and IRFP660 MOSFET is driven. Frequency range between 10kHz ….. 180kHz
TL494 Tesla Coil Drive Circuit Diagram
In the second version, this work, which is a big tesla bobbin, is a buss but it gets bigger spark. The power transistors used IR2110 MOSFET driver instead of transistor to enhance the output of TL494 IGBT (instead of IRFP054N can be used) spark grows in cost as the size grows …
TL494 IR2110 Tesla Coil Drive Circuit Schematic
CAUTION Tesla coils generate high voltage Be careful with capacitor connections + – If you reverse polarity, there may be large explosions at high voltage Fuse Power Line, use protective goggles before operating the circuit

LM358 Sound Detector Circuit
According to media volume on the circuit at the output relay opening and closing sensitivity can be adjusted with potentiometer RV1 RV2 100k.
LM358 opamp amplifier used in the section on the floor of the driver pulled the residence time of the relay CD4528 Rv3 setting and C11, R18 resistor and capacitor values can be adjusted by changing. Ares proteus isis circuit diagram of the circuit and PCB’s drawings.
