Abstract

High-voltage and high-current SiC bipolar diode modules are fabricated and characterized under static and dynamic conditions. The modules are built using 6 \times 6\ \mm^2 SiC chips that are fabricated on 3-in SiC substrates. Individual chips were also packaged in an ISOPLUS™ package and used to perform switching tests on the diodes. The modules have been fully characterized under static and dynamic conditions. These modules are targeted for high-voltage high-frequency applications as well as antiparallel diodes for 6.5-kV insulated gate bipolar transistors, insulated gate commutated thyristors, and injection enhanced insulated gate bipolar transistors.

Abstract

This note considers stability analysis of a class of pulsewidth modulated (PWM) systems that incorporates several different switched mode dc-dc converters. The systems of the class typically have periodic solutions. A sampled data model is developed and used to prove stability of these solutions. Conditions for global and local exponential stability are derived using quadratic and piecewise quadratic Lyapunov functions. The state space is partitioned and the stability conditions are verified by checking a set of coupled linear matrix inequalities (LMIs). [ABSTRACT FROM AUTHOR]
