IXYS Expands Its SMPD Products for Higher Efficiency, Smaller Footprint and Lower Weight for Motor Drives, UPS and Inverters

IXYS Corporation (NASDAQ:IXYS), a leader in power semiconductors and integrated circuits for power conversion and motion control applications, announced today that it is extending the Surface Mount Power Device (SMPD) range to include products that provide the essential building blocks of the power semiconductors for power electronic motor drive systems, the inverter for power supplies and UPS, and the power stage for micro inverters and inverters.

The IXYS SMPD, which has been in volume production since its introduction a year ago, is an innovative power module which can be easily surface mounted on a Printed Circuit Board (PCB) using standard pick and place and reflow soldering process. It is a preferable automated PCB assembly process for the industry without costly screws, cables, bus-bars or hand soldered contacts that have been used for standard power modules in the past. Additionally, these products are much lighter in weight than comparable standard power modules.

“Since its inception the SMPD has proved extremely attractive to our customers who needed a better power module solution for automated SMD assembly because it is a lower weight, lower cost, smaller sized package - ‘MORE POWER, LESS PACKAGE’. Using our proprietary highly thermally efficient substrate technology, we can build any power circuit on it with full electrical isolation. We provide full design flexibility to our customers. We can use all our silicon technologies - rectifiers, thyristors, MOSFETs, XPT IGBTs, reverse blocking IGBTs and SiC diodes in any desired configurations,” commented Mr. Bradley Green, President of European Sales and Business Development at IXYS.

This new range of products is targeted to provide SMPD modules for each of the rectifier, brake and inverter stages of a motor drive or micro-inverter system which can be located separately on the PCB to facilitate reduced heat sink size, weight and cost. The SMPD advantage allows faster assembly cycles and the chip scale packaging reduces material waste inherent in single module solutions.

“Our 'MORE POWER, LESS PACKAGE' design philosophy is targeted to make use of leading edge material technology to improve our customers’ solutions in a world more sensitive to the environmental impact of product design. By lowering the weight significantly, typically by 50%, we help reduce the carbon footprint for our customers who are using this family of SMPD products,” added Mr. Green.

Examples of the building blocks that can be used to create a motor drive or micro-inverter are:

  For the Rectifier Stage:
Single Phase DLA100B1200LB 100A 1200V (4 diodes in a single package)
Three Phase DMA90U1800LB 90A 1800V (6 diodes in a single package)
Brake Stage (Boost topology):
IXA20RG1200DHGLB 20A 1200V XPT IGBT and diode
IXA30RG1200DHGLB 30A 1200V XPT IGBT and diode
IXA40RG1200DHGLB 40A 1200V XPT IGBT and diode
Inverter Stage (Dual IGBT in half bridge topology with anti-parallel diodes):
IXA20PG1200DHGLB – IGBT Phase leg 20A 1200V
IXA30PG1200DHGLB – IGBT Phase leg 30A 1200V
IXA40PG1200DHGLB – IGBT Phase leg 40A 1200V

By using a simple combination of the above products, a motor drive system or micro-inverter with optimized silicon content up to 11kW in power rating can be achieved with a faster time to market and minimal investment due to standard surface mount assembly processes currently existing in normal PCB assembly lines.
