A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

GaN power transistors can shrink AC‑DC power supplies and cut losses but, to get the best out of them, their gate drive waveform needs careful attention. As a German team pointed out at ISSCC, GaN ...

In power converters, pulse-drive circuits transmit the pulses a controller generates to the power transistor. Driver circuits must both transmit the controller's switching on/off signals with galvanic ...
