Power modules keep their cool
Isolated power modules are designed for PCB soldering and use baseplate-free technology to guarantee high reliability and isolation with the lowest overall thermal resistance
The soft-punch-through (SPT) chip design is based on a planar-gate/punch-through IGBT technology. It offers benefits such as lower switching losses, smaller chip sises (and therefore lower cost) for the same current-handling capability, positive temperature coefficient and a high switching frequency suitable for many applications, including the specialised requirements of welding systems.
Semix has been developed for fast, solder-free mounting.
The AC and DC terminals are located at opposite ends of the module and are all a standardised 17mm height from the base, allowing a low-inductance design and a simplified bus structure.
Its spring contacts allow the control PCB with driver etc to be mounted directly onto the power module without any wiring or soldering.

New facility meets Chinese market demands
A record growth in annual turnover of 40% in China has prompted Semikron to open a new Chinese headquarters and production facility in the city of Zhu Hai
These IGBT and rectifier modules open up new opportunities for creating flat and compact frequency inverter designs (AC/DC drives from 15 to 110kW).
Due to their identical case heights, the IGBT modules and input bridge rectifier modules can be directly connected using bus-bars instead of wires, saving 15% volume compared with conventional rectifiers, reducing stray inductance and halving production time.
The diverse Semix product line is available in four compatible case sizes of the 600, 1200 and 1700V IGBT modules from 75 to 600A and are available in half-bridge, six-pack and chopper topologies.
The Semix controlled and uncontrolled rectifier modules are offered in cases with an identical 17mm height.
More options are therefore available for inverter designs, from standard drives and power supplies through to customised applications.
Semikron also offers free support with Semisel, an online calculation and simulation tool that developers can use to select the most suitable power semiconductor for a specific application.
