MiniSKiiP® Benefits

The unique mechanical design offers outstandingly easy assembly and service friendly spring contact technology. Opposed to conventional solder or press-fit modules with specific equipment required (automated presses, wave-soldering machine), no dedicated tools are needed for MiniSKiiP assembly. Instead, one or two screws connect everything from driver to heatsink.

Assemble the printed circuit board (PCB), power module and heatsink in one mounting step. With higher flexibility, the PCB no longer needs to holes for solder pins or press-fit connections. The springs connecting the PCB and power circuitry are far superior to soldered joints, increasing lifetime under thermal or mechanical stress. Thanks to the high mechanical pressure provided by the springs, achieve an airtight, reliable electrical connection.

MiniSKiiP® Production Process

MiniSKiiP® Short Facts

  • Available in six different housings
  • Low cost assembly, high production run rate, high yield
  • Small and compact system designs
  • Excellent reliability and long product life time
  • Up to 110kW Motor Drive power, 300kW Solar inverter power and 100kVA UPS power

MiniSKiiP® Key Features

  • Solder-free SPRiNG technology for fast and easy assembly
  • Baseplate-less design allows cost efficient designs and high thermal performance
  • Easy and flexible PCB routing, no pin holes required
  • Comprehensive topology portfolio: CIB, bridge rectifier, sixpack, twelvepack, H-bridge, Half-Bridge, 3-level NPC/TNPC/ANPC, boost topologies (boost chopper, Flying Capacitor Boost, Symmetrical Boost)

MiniSKiiP® Applications

With two decades of field experience and more than 50 million modules in the field, this module platform has proven successful in all standard applications. Key applications include motor and servo drives, solar inverters with 1000VDC and 1500VDC, UPS systems and welding machines. Thanks to the excellent reliability of spring contacts, applications such as agricultural vehicles or yaw and pitch drives in wind turbines benefit from MiniSKiiP technology as well.

MiniSKiiP® Product Range

The MiniSKiiP portfolio ranges from 600V to 1700V and 4A to 600A nominal chip currents. Along with the consolidated IGBT3 and IGBT4 portfolio, the latest IGBT Generation 7 and Silicon Carbide components are also equipped.

Motor drive topologies (CIB/sixpack/twelvepack/half-bridge) and accompanying full-, half- and un-controlled rectifiers and choppers.

For solar, a full range of NPC, TNPC, symmetrical boost and flying capacitor boost topologies are based on the latest 950V IGBT Generation 7 chipsets. The new generation enables the highest power density in string solar and energy storage inverters.

NPC and symmetrical boost topologies for UPS applications, based on fast-switching 650V IGBTs and diodes, enable increased power density up to 100kVA.

What’s more, the latest chip technology, such as hybrid silicon carbide power modules, push the efficiency and power density to even higher levels. For fast evaluation, test PCB boards are available for most power modules. All power modules are also available with pre-applied High Performance Thermal Paste, a benchmark thermal interface material.

Our Solution for Motor Drives

The latest IGBT T7 chip generation:

  • 20% lower forward voltage drop (Vce,sat) compared to IGBT 4
  • 25% smaller chip size compared to IGBT 4

Example housing size jump: 50A CIB module in 35% smaller package

In the motor drive application:

  • Up to 20% lower losses at the same output power, or up to 20% higher output power

Higher efficiency, increased power density and lower system cost
