Panasonic Corporation (Panasonic) and Sansha Electric MFG Co.,
Ltd. (Sansha Electric) today announced that they have developed a
very compact Silicon Carbide (SiC) power module together with
highly efficient operation of power switching systems. The SiC
power module has sufficiently good reliability and greatly helps to
reduce the size of power switching systems such as industrial
inverters and power supplies.

SiC is very promising due to its superior material properties
and is expected to reduce the power consumption of various
switching systems. These high power switching devices need to be
packaged into a so-called power module in which multi transistors
are integrated. The developed SiC power module is based on the
following proprietary technologies.
1) Panasonic’s SiC DioMOS (Diode-integrated MOSFET) has the
features of a reverse conducting diode without any external diode.
The total chip area of SiC is reduced by half from a conventional
SiC, which helps to reduce the total footprint of the module. The
improved design of the DioMOS structure reduces on-state resistance
to 6mΩ at 150A.
2) Sansha Electric’s Techno Block module technologies utilize
solder bonding for the SiC chips without any wire bonding. This
configuration reduces the height of the module by half from
conventional ones as well as they can serve three times better
endurance of power cycling tests.
The fabricated SiC power module integrates two SiC transistors
into one package and achieves 6mΩ of on-state resistance with a
rating current/voltage of 150A/1200V. The total volume of the
module is reduced by one third compared to a conventional SiC power
module. These features together with good reliability enable very
compact and highly efficient power switching systems.
These research and development results will be presented at the
exhibition ”The Applied Power Electrics Conference 2015,” from
March 15 to 19, 2015 (Charlotte, North Carolina, U.S).
