In the News: Prolonged Silicon Carbide Integrated Circuit Operation in Venus Surface Atmospheric Conditions
The prolonged operation of semiconductor integrated circuits (ICs) needed for long-duration exploration of the surface of Venus has proven insurmountably challenging to date due to the
∼ 460 °C, ∼ 9.4 MPa caustic environment. Past and planned Venus landers have been limited to a few hours of surface operation, even when IC electronics needed for basic lander operation are protected with heavily cumbersome pressure vessels and cooling measures. Here we demonstrate vastly longer (weeks) electrical operation of two silicon carbide (4H-SiC) junction field effect transistor (JFET) ring oscillator ICs tested with chips directly exposed (no cooling and no protective chip packaging) to a high-fidelity physical and chemical reproduction of Venus’ surface atmosphere. This represents more than 100-fold extension of demonstrated Venus environment electronics durability. With further technology maturation, such SiC IC electronics could drastically improve Venus lander designs and mission concepts, fundamentally enabling long-duration enhanced missions to the surface of Venus.

White Paper: A Bidirectional DC-DC High Frequency Dual-Half Bridge Series Resonant Converter: Design, Simulation and Experimental Results
This paper looks at a bidirectional high frequency dual-half bridge series resonant converter (DHBSRC) designed for energy storage application. Two half-bridges are connected through LC resonant tank and HF transformer. Power flow of the converter is controlled using phase shifted gating scheme with 50% duty cycle. Operating principle, analysis and design of DHBSRC are presented in the report. This project also looks at the benefit of using new generation SiC MOSFETs that have many promising properties like larger bandgap and higher thermal conductivity, which predicts lower conduction losses and higher efficiency of converter.

White Paper: Forward Current-voltage Characteristics Simulation of 4H-SiC Silicon Carbide Schottky Diode for Power Electronics
Forward current-voltage characteristics of 4H-SiC Schottky diode with Ni Schottky contact have been simulated based on in the physical analytical models based on Poisson’s equation, drift-diffusion and continuity equations. On the base of analysis of current-voltage characteristics in terms of classical thermionic emission theory it is established that the proposed simulation model of Schottky diode corresponds to the “ideal” diode with average ideality factor n≈1.1 at low temperature ∼300 K. It is determined that effective Schottky barrier height equals 1.1 eV for Ni/4H-SiC Schottky diode. Download paper.
