Suitable for power conversion in industrial equipment converters such as UPS, welding machines, and power conditioners

ROHM Co., Ltd. has newly developed a total of 21 types of 650V withstand voltage IGBTs, including the “RGTV series (short-circuit withstand capability holding type)” and “RGW series (high-speed switching type)”, which simultaneously achieve low conduction loss and high-speed switching characteristics.

It is optimal for power conversion in general-purpose inverters and converters for industrial equipment such as UPS (Uninterruptible Power Supply), welding machines, and power conditioners, as well as consumer equipment such as air conditioners and IH (Induction Heating).

By employing thin wafer technology and a proprietary structure, the newly developed series simultaneously achieves the industry's highest standards in conduction loss and high-speed switching characteristics, which are typically in a trade-off relationship.

By utilizing thin wafer technology, this series has reduced the wafer thickness by % compared to existing products. Furthermore, by adopting ROHM’s proprietary structure with miniaturized cells, it was possible to simultaneously achieve industry-leading low conduction loss and high-speed switching characteristics.

Soft switching with smooth OFF transitions was achieved by optimizing the internal structure of the device. As a result, voltage overshoot occurring during switching can be reduced by 50% compared to standard products, eliminating the need for external gate resistors or snubber circuits previously required to suppress overshoot, thereby reducing the number of components. Since the overshoot countermeasures previously required when using IGBTs are no longer necessary, this contributes to reducing the design load on the application side.
