This is Part 2 of my video series on designing and building a Solid State Tesla Coil (SSTC).

In this video, I'm going to show the following:

-Finding the resonant frequency of a Tesla Coil with a Signal Generator and Oscilloscope

-Problems with single-MOSFET designs, and why they should be avoided

-How to design/build a half-bridge inverter to drive the primary coil

-Signal conditioning with inverted schmitt triggers and RC delay circuits to change

phase / duty cycle

-Using dedicated MOSFET gate drivers and coupling their output with a signal transformer

to isolate the driver logic from the half bridge

-Design of an interrupter to modulate the output of the coil

Hardware used:

-2"x12" PVC secondary former with 1,200 turns of 30 gauge wire

-4-turn, 3.5" diameter primary coil

-Approximately 6"x6" aluminum plate as a ground plane

-TLC555 (High speed timer for up to 2.1 mHz)

-NE555 (Low speed timer for interrupter - 100 kHz max)

-CD74HC14E Hex Schmitt Trigger inverter for signal conditioning

-TC4422 MOSFET Driver chips (9A max / 18V vcc max)

-IRF540 (100V max) MOSFETs for half-bridge

-MUR120G diodes for half-bridge

-30mm toroid wound with 25-turn trifilar winding of 26 gauge wire

for the gate drive transformer

In the third video, I'm going to cover how to use secondary coil feedback to drive

the primary coil, signal phase shift, and the construction of a full-bridge inverter

powered with mains voltage (120V).
