Full-Bridge Module
The EHT Full-Bridge Module is a IGBT or SiC MOSFET-based full bridge designed to drive resistive, inductive, and resonant loads. The EHT full bridge includes independent, fiber-optically isolated gates for each leg of the full bridge allowing the user to control which bridge legs are in forward conduction vs freewheeling. Integrated safety features prevent shoot-through.
The EHT full bridge simplifies electromagnetic coil driving and plasma generation allowing customers to rapidly develop and deploy a power system for their application.

Fiber-Optically Isolated Gate Drive
EHT’s patented precision gate drive produces clean switching waveforms. The low jitter gate (< 5 ns) drive allows these units to be operated in parallel to drive even higher currents into your load. The precision gate drive produces very fast switch transitions, which significantly decreases the switching losses. At high frequency operation, they are significantly more efficient than competing switches on the market. (FT-1s are included)
