Simulation and Analysis of Si Schottky Diode Family in DC-DC Converter

Abstract

The unipolar-based devices, silicon schottky (Si) and silicon carbide schottky (SiC) power diodes are investigated for their reverse recovery transient responses and the effects on the switching losses of the FET in the DC-DC converter. Two inductive load chopper circuits are simulated with different test diodes using PSpice software to determine the effectiveness and superiority in each of the devices. All parameter settings are consistent for both converter circuits. The results have shown that the SiC diode has higher energy savings of more than 73.13 % in turn-off switching losses. This eventually corresponds to the reduction of 96.16 % in FET turn-on peak power dissipation of SiC converter. However, there is a minor drawback in drain voltage overshoot of the converter. Some detailed analyses are presented in the paper.

Characteristics and Utilizatation of PVA/Mn Ploymer Nanocomposite as the Schottky

“…It has a low barrier potential compared with PN diode. Also, it widely utilized in frequency mixing and RF power detection circuits In addition that have numerous specification on other diodes such as low forward voltage drop, less heat, high efficiency, high current density, and low capacitance, fundamentally exhibit ultralight speed characteristics, because they are majority-carrier devices and the minority-carrier storage the effect is negligible [8][9][10][11].…”

Fabrication of Polymer Based Schottky Diode Using Pani/Ag Nano Composite

“…Molecular-scale nanoelectronic devices including diodes, bistable switches and nanowires have been fabricated and characterized in chemistry laboratory. Among these devices considerable attention is given to the fabrication and characterization of Schottky diodes using polymer and metals because Schottky diode offer several advantages over other diodes such as low forward voltage drop, less heat, high efficiency, high current density and low capacitance [1][2][3][4].Among all conducting polymers, polyaniline (PANI) and its derivatives are more attracted because of its chemical stability, simple preparation, high conductivity and low cost [5][6][7]. Bulk silver shows the highest electrical conductivity among metals at room temperature and it is an adept for producing conducting composites [8,9].…”
