Gate Drive Circuit Suitable for a GaN Gate Injection Transistor
نویسندگان
چکیده
A GaN gate injection transistor (GIT) has great potential as a power semiconductor device. However, GIT diode characteristic at the gate-source, and corresponding drive circuit is thus required. Several studies in literature have proposed circuits with speed-up capacitors, but adding these capacitors complicates circuit, increases both reverse conduction losses. Moreover, driving such becomes more susceptible to false turn-on. In this paper, suitable for without capacitor proposed. This type can provide high-speed switching, exhibit low loss loss. The also high immunity against turn-on stable gate-source voltage before after startup. of calculated its validity confirmed experimentally. Furthermore, compared conventional circuits. result shows that improved by up 50 %, type. Finally, experimentally tested buck converter switching frequency 150 kHz. entire be reduced 9.2% 250 W,
