The Miniskiip IPM (intelligent power module) from Semikron has been developed for inverter applications of up to 15kW.

The 1,200V Miniskiip IPM weighs 55g, has an area of 59mm x 52mm and an overall height of 16mm.

Its design is said to yield optimum switching properties with regard to electromagnetic interference.

The connection technology allows for the development of compact inverters and reduced production costs.

To achieve the high power density offered in the Miniskiip IPM module, the power semiconductor chips and the DCB are thermally connected to the heat sink by way of an efficient pressure contact system.

Since the module does not contain a base plate, the thermal resistance is much lower than in any other IPM with base plate.

The integrated SOI driver is mounted directly onto the DCB and connected to the gate terminals of the power transistors by short conductor lines via optimised gate resistors.

These short connections ensure harmonious switching behaviour and reduce electromagnetic interference.

As a result, less complex protection measures are needed to comply with the electromagnetic compatibility requirements.

The short paths result in low parasitic inductances, which in turn mean lower over-voltages in the module, allowing for higher DC link voltages and greater efficiency.

The Miniskiip IPM module and the power circuit board are mounted to the heat sink using a single standard screw.

The entire power, gate and auxiliary connections are made by way of pressure contacts to the PCB rather than soldered contacts.

The removal of solders further improves the quality of the entire construction and offers a high degree of reliability.

The 1,200V six-pack Miniskiip IPM has a high-voltage driver IC and features Trench-Field-Stop IGBTs, which are optimised for low switching losses and high current densities.

At a rated current of 61A, an output power of up to 15kW is possible.

The company also offers 600V Converter-Inverter-Brake versions.

The modules fully comply with the requirements of the EU RoHS directive.

SEMIKRON, a private and financially independent family enterprise, was founded in 1951 and employs 2,900 people worldwide. The headquarters is located in Nuremberg, Germany. The company develops and produces reliable and efficient power electronic components and solutions for wind power generators, solar power, electric and hybrid vehicles, power supplies, industrial applications, electric drives, welding machines, lifts, conveyor belts and the rail industry. As a significant innovator in the power electronics sector, many of SEMIKRON’s progressive developments have been accepted as industrial standards.

A global network of 35 companies, production sites and solution centres guarantees fast and competent on-site customer support and service. The products range from 1kW to 10MW: chips, discrete diodes/thyristors, power modules (IGBT/MOSFET/diode/thyristor) to customer-specific solutions and integrated power electronic systems.  

According to a survey carried out by BTM Consult Apes, the total wind power capacity installed until 2009 was 122GW. 57GW comprises semiconductors from SEMIKRON.

As the market leader in the field of diode/thyristor semiconductor modules, SEMIKRON enjoys a 37 per cent share of the worldwide market.*
