System for Evaluation of a Depletion-mode SiC Power JFET
نویسنده
چکیده
This paper presents the system for evaluation of a depletion-mode silicon carbide (SiC) power junction field-effect transistor (JFET). The main part of the system is a dc-dc step-down converter which simulates realistic operating conditions of switching devices in a synchronous buck configuration. In order to ensure a proper operation of the synchronous buck converter test board, a precise time-delay pulse signal generator is developed as well as a small flyback-based power supply circuit. The demanding requirements of the aforementioned parts of the developed system are presented and discussed. The operation of the complete system is verified by measurements performed under simple operating conditions. The benefits and drawbacks of the developed system dictate the future plans that are briefly discussed.

Evaluation of capacitance-voltage characteristics for high voltage SiC-JFET
Capacitance between terminals of a power semiconductor device substantially affects on its switching operation. This paper presents a capacitance–voltage (C–V) characterization system for measuring high voltage SiC–JFET and the results. The C–V characterization system enables one to impose high drain-source voltage to the device and extracts the capacitance between two of three terminals in FET...

The reverse conduction mode of operation of the SiC trench JFET allows for diode-free synchronous rectification. This paper shows that the reverse conduction mode is an inherent property of the device caused by diffusion of electrons through the source fingers under conditions of moderate gate-drain diode forward bias. Experimental results confirm the expectations for a vertical-channel SiC JFE...

The omnipresent trend of increasing the power density of inverter technology lead to new developments in semiconductor material. As most of the benefits come from higher operating junction temperatures, it is mandatory to restrict the inverter design to peripheral components capable to work in these high temperature conditions. Eliminating the needs for large DC-link capacitors, the matrix conv...
