DRSSTC / SSTC Tesla Coil Full-Bridge IGBT Inverter Module with GDT Driver – Ready Power Stage

Tesla Coil Full-Bridge Inverter Power Module (DRSSTC / SSTC)

Complete high-power inverter stage designed for solid state Tesla coils and resonant high-frequency systems.

This finished full-bridge inverter module provides the main switching power stage required for building a DRSSTC or SSTC Tesla coil. It integrates high-current IGBTs, isolation gate drive transformer input and bus protection capacitors into a ready-to-wire assembly.

The phase orientation is preconfigured on the board, eliminating the need for manual phasing. Simply connect the driver and power supply to operate, making it suitable for both experienced builders and advanced hobbyists.

Main Features

• Full-bridge (H-bridge) inverter topology
• Designed for SSTC and DRSSTC Tesla coil drivers
• Isolation transformer (GDT) gate drive input
• Pre-phased connections — no phase matching required
• High-current screw terminals for power and output
• Integrated rectifier allows direct AC mains input (via proper supply stage)
• Large heat sink with fan mounting capability
• PCB mounting holes for easy installation

Power Stage

• 4 × G4PC50UD IGBT power transistors
• Full bridge switching configuration
• Snubber / absorption capacitors installed
• Low-inductance bus layout
• High current output terminals

Cooling & Construction

• Thick aluminum heatsink
• Fan mount provision
• Heavy copper PCB traces
• Screw terminal connections for reliability

Typical Applications

• DRSSTC Tesla coil power stage
