15:15 Switching Behavior of SiC-MOSFETs in High Power Modules
M.Sc. Florian Störmer, University of Rostock, Rostock, Deutschland
To evaluate the switching behavior as well as switching losses in high power modules, a single chip 40 A SiC-MOSFET was tested with high commutating inductance. The single SiC-MOSFET need to slown down because of the increased oscillations and overvoltage during turn-off. To reduce these higher switching losses, new control concepts have been developed and tested.
15:15 The Challenges of Using SiC MOSFET-Based Power Modules for Solar Inverters
Dipl.-Ing. Matthias Tauer, Vincotech, Unterhaching, Deutschland
This paper examines SiC MOSFETs as a viable option for meeting the rising demand for faster switching and greater efficiency in 1500 V solar applications. It looks at their benefits - SiC MOSFETs enable deeper integration and greater power density - and their drawbacks in terms of switching performance and thermal conductivity in power module applications. The latest generations of devices' intrinsic properties appear to inhibit performance and reliability.
15:15 Low Inductive SiC Power Module Design Using Ceramic Multilayer Substrates
M.Eng. Thomas Huber, University of Applied Sciences Landshut, Landshut, Deutschland
This paper presents the module design of a novel 600 V / 200 A full silicon carbide (SiC) half-bridge inverter module. The module is realized with a ceramic multilayer substrate which allows an ultra-low power loop stray inductance value of 1.3nH. Thermal simulations reveal that the thermal resistance is not increased by the multilayer design. Due to the heat spreading within the copper layers, the thermal influence of an additional ceramic layer can be compensated.
15:15 Very Low Stray Inductance, High Frequency 1200V_ 2 mOhms SiC MOSFET Phase Leg Module
Dipl.-Ing. Serge Bontemps, Microsemi Power Module Products, Bruges, Frankreich
This paper presents the characterization of a new 1200V / 2 mOhms Full SiC MOSFET phase leg module featuring a very low stray inductance within the standard 62 x 108 mm2 package. This module is built with an AlSiC base plate, AMB on Si3N4 substrates and the SiC MOSFET die are silver sintered for highest thermal performance and reliability. This 1200V/600A module achieves a parasitic inductance below 5 nH
15:15 Comparative Study of Full SiC Power Module in 1MHz, 600V, 50A Switching Operation
Kei Hayashi, Osaka University, Suita, Japan
This paper develops 1200V, 50A full SiC half bridge power module, witch embeds C snubber and gate resistor. Embedded C snubber suppress surge voltage in fast switching operation, and gate resistors avoid parasitic gate oscillation of parallel connected SiC MOSFET in the module. 1MHz switching operation of developed module with 600V DC-Link voltage and 100A peak to peak load current is experimentally confirmed. In addition, two commercial power modules are applied with same test condition to evaluation developed power module.
15:15 3.3kV SiC Hybrid Module with High Power Next Core (HPnC) Package
Lukas Kleingrothe, Fuji Electric Europe, Offenbach am Main, Deutschland
Recently main requirements for power conversion system are further downsizing and higher efficiency. To satisfy these requirements, enhanced power density of power modules should be the key to succeed. In this paper, 3.3kV SiC-Hybrid module with High Power next Core package, which can realize lower switching loss than Silicone, has been described.
15:15 High Reliable 1700V Full SiC Power Module
M.Sc. Kenji Hayashi, Rohm, Kyoto, Japan
1700V, 250A full SiC power module composed of Silicon Carbide (SiC) MOSFETs and SiC Schottky diodes has been launched. We utilized standard module package which is used in the market widely like as mass-produced ROHM's BSM300D12P2E001. Especially the 1700V full SiC module could pass over 1000 hours lifetime of HTRB and HV-H3TRB test. The ROHM's newly module has high reliability for usage in high humidity environment.
15:15 Analysis of 1200 V Si-SiC-Hybrid Switches for Resonant Applications
M.Sc. Michael Meissner, Helmut-Schmidt University, Hamburg, Deutschland
Hybrid switches consisting of a silicon IGBT and a silicon carbide MOSFET are a promising approach forpower loss reduction in resonant topologies. Potentials and performance are analysed and discussed indetail.
15:15 Simulation Based Design of SiC MOSFET Power Modules for EV/HEV Traction Inverter Applications with Test Validation
Dr. Roy Davis, ON Semiconductor, Ann Arbor, USA
In this paper, we illustrate the process of SiC MOSFET half-bridge module design for inverter applications using simulation tools that address electrical and thermal performance concurrent with semiconductor device design. Validation of simulation results by testing a prototype inverter is reported. We conclude that this approach yields proper dimensioning of parallel devices while achieving efficiency and junction temperature targets based on projected device characteristics, leading to high performance, cost-effective module products.
15:15 Sintering Cu Paste Die-Attach for High TJ Power Devices
Prof. Shijo Nagao, Osaka University, Ibaraki, Japan
Metal sintering paste of Cu submicron/micron-particles is considered as a heat-resistant die-attach material for emerging wide bandgap power semiconductors, with its excellent electrical and thermal conductivity as well as its affordability. In the present work, a Cu particles paste was used for die-attach of SiC-MOSFET. The specimens of sintered Cu bonding structure were subjected to high temperature storage test, thermal shock test and power cycle test. Long?term reliability of the bonding was evaluated by die-shear strength test, phase analysis, microstructure observation, and electrical resistance.
