8 Things to Consider Before Designing a Gate Drive Transformer
Several important factors need to be considered when designing an optimized gate drive transformer (GDT). This article discusses several GDT design considerations, as well as ideal applications for their use. Two of the critical components to control when designing a gate-drive transformer are the leakage inductance and distributed capacitance. High leakage inductance and distributed capacitance...Continue reading

Gate Drive Transformer Pulse Response Characteristics
A gate drive transformer must reproduce the shape of an input pulse as accurately as possible at its secondary terminals. The performance of a gate drive transformer’s pulse characteristics is specified in terms of its effect on the shape of the pulse input current/voltage. It is important that the transformer must reproduce the shape of...Continue reading

Gate Drive Transformers and Circuits
A gate drive transformer is optimized for transmitting rectangular electrical pulses with fast rise and fall times to activate or deactivate a switching device. Despite various floating channel MOSFET/IGBT driver ICs being available, a transformer-coupled gate drive is still the better option to use for high power applications for many reasons. For example, due to the multiple...Continue reading
