2019, May – High power applications in the fields such as renewable energy and industrial drives require reliable and scalable power modules with high power density and low stray inductances. In order to fulfill these requirements, the concept of the well-known and successful HVIGBT LV100 package has been transferred and adapted to the needs of renewable and industrial applications.
2019, February – Generally, the emerging SiC technology is associated with very high switching frequencies resulting in compact converters. This article focuses on this switching behavior of SiC devices and compares Full SiC and Hybrid SiC with the behavior of a silicon device. All considered modules are rated for 3.3 kV and similar current ranges to give a fair and illustrative comparison. Finally, the article gives an outlook on future higher-voltage 6.5 kV SiC technology.
2019, January – The railway applications require components with high quality and high efficiency, especially the converter drives should have reliable and robust switching devices. It is an established practice to utilize 1700V IGBT modules to operate directly on the catenary with the DC voltages below 1000V or in 3-level configuration with catenary DC voltages above 1000V.
2018, December – Applications such as elevator drives or servomotors have several special requirements. One on hand, high efficiency is important, while on the other hand, the inverter unit be resilient to the different types of load cycling. Furthermore, the inverter must be designed as compact as possible. NX7 CIB modules aim to address these challenges.
2018, June – Mitsubishi Electric has added a new transfer molded SMD type Intelligent Power Module to its line-up – the MISOP™. The MISOP™ is an ideal solution for high performance inverters in the range of 100W which require a high degree of compactness, high efficiency and easy assembly.
2018, March – For power electronic systems like industrial drives and converters for renewable energy applications, the major system requirements are: high reliability, high efficiency, high power density and competitive costs. In order to meet these requirements, power loss reduction is a key factor. Power loss reduction enables designs with higher power densities and lower IGBT junction temperatures. As a result, higher reliability can be achieved and the cooling system can be accordingly optimized. Therefore, Mitsubishi Electric has developed the new 1.7 kV 7th generation IGBT modules with improved performance.
2018, January – Mitsubishi Electric is developing a new Full SiC device rated for 3.3 kV and 750 A. The device comes in the most recent LV100 package, which is especially suitable for traction application and modular converter designs. This article introduces the new Full SiC device and demonstrates the benefits in traction applications.
2017, December – Mitsubishi Electric has developed high performance 4500V IGBT power modules providing reliable solutions for medium voltage drive, railway and power transmission applications.
2017, October – The overall system performance is undoubtedly influenced to a significant extent by the choice of the power semiconductor technology employed. For conventional IGBT modules, the recent improvements in the VCEsat vs. Eoff trade-off shows a tendency towards saturation and hence the performance improvement of upcoming IGBT chip generations do not indicate a significant step in efficiency improvements anymore. With the new G1-IPM series it is possible to obtain substantial system efficiency improvement by utilizing an advanced Si-IGBT chip and implementing an adaptive gate control.
2017, May – In various power electronic applications, the lifetime of the converter is a key factor for consideration for estimating the total cost. Particularly at intermittent load profiles the lifetime of a power converter is limited by the temperature cycling capability of the power module packages due to the interconnection of materials with different CTEs (Coefficient of Thermal Expansion). The 7th gen. IGBT modules are based on the new SLC packaging technology with a material composition based on matching CTEs which result in the highest thermal cycling capability.
2016, November – Industrial drive applications require scalable IGBT modules to simplify the design and to provide the possibility of utilizing the same components like driver boards and bus bars for different inverter power ratings. The Mitsubishi NX-series 7in1 IGBT packages provide such scalable solutions combined with high power density and simplified inverter assembly.
2016, September – A novel family of compact Intelligent Converter-Inverter-Brake-modules was developed. This new DIPIPM+™ series incorporates optimized IGBT- and FWDi-chips, low voltage and high voltage driver ICs in a compact transfer molded dual-inline package. The new DIPIPM+™ series is providing smart answers on the 2 key questions a designer is facing when developing a new inverter design: How to reduce the system cost? How to reduce the inverter size by compact design?
2016, April – Three level topologies have demonstrated higher efficiencies, filter optimization potential and the capability of handling high DC-link voltages. To maximize the advantages offered by the 3-level topologies, Mitsubishi Electric offers new power modules which unlock the potential to realize innovative solutions for different power segments.
2016, January – A very compact Dual-In-line Package Intelligent Power Module SLIMDIP with ratings of 5A and 15A /600V has been developed employing Reverse Conducting (RC) IGBT chip technology. This technology integrates the required freewheeling function for inductive loads into the developed RC-IGBT chip and, hence, makes the Diode that usually is connected antiparallelly to a conventional IGBT redundant.
2015, April – By using SiC-based semiconductors the performance of power electronic systems can be drastically improved.
2015, February – A growing demand for 3-level inverter technology combining reduced power loss and increased power capacity is originating from power conversion applications like wind and PV inverter as well as from industrial equipment such as uninterruptible power supplies (UPS) and recently active frontends of 4-quadrant drives.
2014, August – Dedicated IGBT-modules for high switching frequency operation have been successfully introduced to the market over the past years. Typical applications are X-ray generators, CT-scanners, induction heating, welding, plasma cutters or inverters for isolated or contactless electrical power conversion.
2014, June – This article presents 2 new Mitsubishi Electric power module series for Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) power-train inverter and converter applications.
2014, March – In Multi-Axis Servo-Drives several servo amplifiers are operating from a common DC-link power supply. Mechanically those servo amplifiers usually are mounted in a so called “book-shelf-arrangement” in a common mechanical rack. This specific construction principle is providing a limited space at each inverter’s backside for cooling the power semiconductors.
