When the Entwicklung der Antriebssysteme von E-Fahrzeugen zunehmend Siliziumkarbid (SiC)-Leistungsbauelemente is established. It is a war that is swingy, but less small. ROHM has a rearrangement with a 2-in-1 SiC module TRCDRIVE pack™.

It is a matter of climate-neutral and energy-efficient energy efficiency that is one of the most important costs for a green energy. If we play the story of the electric drive, efficiency and lighting of an electric role, the Verbreitung of the electrofahrzeugen of the next generation (xEVs) is intended and universal that affects the neutrality of the substance. Connecting electrical appliances is the improved operation of the antenna aimers of larger wirings, allowing the Reichsweite to remain high and the size of the board batteries to be reduced.

SiC as Schlüsselcomponents der Elektromobilität

Silizium carbide (SiC) plays a major role in this. For SiC construction elements, a large renovation is a small pleasure with a smaller building construction. ROHM solves this dilemma with the TRCDRIVE pack™.

TRCDRIVE pack™ is a marker for the SiC module from ROHM, which is specially developed for traction expansion and uses a single construction for maximum heat reduction. The integration of ROHM’s 4th generation SiC MOSFETs with new, wider standards for reduced branching density, which is 1.5 times higher than conventional SiC modules. It is important to take care of the miniaturization of the Wechselrichtern for xEVs.

The TRCDRIVE pack™ module from ROHM is a Halbbrücken module, with SiC FETs from the four best generations. This module is so compact that it has a high current density and low beet consumption. With modules that can be carried out by the automotive industry, it is easy to walk in and expect high quality.

The TRCDRIVE pack™ goes through the seine Leistungsfähigkeit aus. A single, high temperature housing ensures easy mounting and high current density. Due to an optimized internal arrangement, there is a low inductance of 5.7 nH. This is illuminated by a two-layer bus-bar structure, where the Strompfad maximizes. Durch einen sehr geringen Einschaltwiderstand (R_DS(on)) a branch current tight of 19.1 Arms/cm² can be achieved. The module is suitable for voltages of 750 V and 1,200 V.

With a power of 300 kW and a balanced power supply, the Modul dazu derives, which are the most powerful features of Traktionswechselrichtern with miniaturization, higher efficiency and less energy consumption. The module has control signal terminals with push pins, which make an easy connection to the gate control board from the outside.

Product spectrum

TRCDRIVE pack™ will be delivered in March 2025 with a series of zwölf models in various housing sizes (small / large) and mounting adapters (TIM: Wärmeableitblech / Ag-Sinter) integrated. You can use ROHM as a 6-in-1 product with integrated kitchen appliances. This is possible due to the rapid design of Antriebswechselrichttern and the marketing of models, which are based on a design specification.

Umfassende Anwenderunterstützung

ROHM offers excellent support for the purchase of electrical equipment that is suitable for your own engine equipment. It is a great experience to use a … If two evaluations are carried out, there are two double-pulse tests and other 3-phase complete steps, which can lead an evaluation to a practical bed.

The evaluation kit for Doppelpulse tests improves the quality of the external anchorage, and makes the necessary changes to the clamps. There was no special attention to inheritance orders, there was a Bewertung in verschiedenen Standardumgebungen ermöglicht. The design of the Gate Driver Boards is suitable for each type. 24 Volt, the switching frequency is a maximum of 20 kHz. The business spannung is part of the Stehspannung of the Kondensators/Baulements.

The Evaluation Kit for 3-Phase Complete Bridge Connections provides better performance, improved external terminals as well as advanced capacitors and an integrated cooling system. Further specifications are a Gate-Driver-Board version of typ. 24 Volt, a switching frequency of 20 kHz and a voltage of 900 Volt.

Fazit

ROHM with the TRCDRIVE pack™ series compact, an integrated, warm module with a high current tight connection, which is optimized for xEV tractions and based on ROHM’s own modular technology. The module shown has a miniaturization effect, increasing efficiency and Wenger lung function. ROHM showcased the TRCDRIVE pack™ Series at Electronics 2024 (12 to 15 November in Munich) at Stand 520 in Halle C3.
