Toroidal Gate Drive Transformers
·
·
·
·
Deliver MOSFET / IGBT gate power and timing
signals simultaneously
Directly drive high-side MOSFETs / IGBTs on
busses up to 400V
Excellent risetime, overshoot, and peak current
characteristics
>8 mm minimum creepage and clearance from
drive to gates exceeds safety agency require-
ments for many common applications
·
