Shanghai Luxin releases 650V&1200V Hybrid IGBT single tube series products

Recently, Shanghai Luxin Electronic Technology Co., Ltd. launched 650V & 1200V Hybrid IGBT single-tube series products (40A-75A), targeting applications such as on-board chargers (OBC), photovoltaic inverters, energy storage systems and uninterruptible power supply systems (UPS). The new Hybrid series products combine the main advantages of Shanghai Luxin FinePitch Gen2 IGBT technology and SiC Schottky diodes, with excellent switching speed and extremely low switching losses, especially suitable for high-frequency PFC circuits (such as totem pole circuits) and DC-DC power converters and other topological circuits.

加速技术创新， 产品性能显著提升

As a high-tech enterprise specializing in the design, development and sales of power semiconductors, Shanghai Luxin insists on independent innovation and continuously improves its core competitiveness. After several years of independent research and development and iterative development, Shanghai Luxin's IGBT products have excellent performance and a rich series, covering 650V/1200V/1350V, 10A-275A, single tube/chip/module. Its new generation of FinePitch products has the same performance as the latest generation of H5/F5/CS7/ET7 of international leading brands.

Shanghai Luxin's launch of the 650V & 1200V Hybrid IGBT single-tube series products demonstrates its leading competitiveness in the domestic power semiconductor field.

Shanghai Luxin's Hybrid IGBT series products combine the FinePitch Gen2 IGBT and the freewheeling SiC Schottky diode in a single TO-247 tube. While keeping dv/dt and di/dt basically unchanged, the Hybrid IGBT can significantly reduce switching losses. Compared with the conventional IGBT and silicon fast recovery diode co-sealed solution, the new product can reduce Eon by up to 50% and Eoff by 20%, and can also increase the switching frequency by at least 40% while keeping the output power unchanged. Higher switching frequencies help reduce the size of power inductors and transformers, thereby reducing BOM costs. The Hybrid IGBT series products can directly replace IGBTs of corresponding voltage and current, and can increase efficiency by 0.1% for every 10 kHz switching frequency without redesign.

基于其产品特性，Hybrid IGBT系列产品可作为硅基IGBT和高性能SiC MOSFET方案之间新的选择，与硅基IGBT方案相比，Hybrid IGBT可提升器件效率、电磁兼容性和系统可靠性，同时SiC肖特基二极管能快速换流，而且不会有振荡和寄生导通的风险；与SiC MOSFET方案相比，Hybrid IGBT产品可在性能基本相当的情况下，供应链更有保障并且显著降低器件成本。

At present, the leading domestic on-board charger (OBC) company has introduced Shanghai Luxin Hybrid IGBT single tube into mass production for use in mass-produced OBC products, which has improved system efficiency and optimized system performance.

Market demand drives the power semiconductor industry to explode

Power semiconductors are crucial to the development of new energy vehicles and are the cornerstone of driving electric vehicles and achieving carbon neutrality in future transportation. By 2030, it is expected that more than 50% of newly produced cars will be hybrid or pure electric vehicles.

Driven by market demand, Shanghai Luxin has always focused on the design and application of power semiconductors since its establishment in 2017. After years of dedicated exploration, the company has mastered the core technology of innovative power semiconductors, has independent intellectual property rights and brands, and has obtained nearly 50 independent innovation patents. At present, its products cover IGBT, SGT/SJ MOSFET, SiC and other power devices in multiple voltage segments, and provide system solutions in segmented application fields.

Adhering to the principles of "clean, safe and intelligent", Shanghai Luxin provides numerous power semiconductor solutions for the thermal management systems (PTC, air-conditioning compressor), on-board charger (OBC) systems, auxiliary drive systems and main drive systems of new energy vehicles.

It is worth mentioning that IGBT products need to be strictly controlled in multiple links such as device design, wafer processing, parameter adjustment, FRD matching, and packaging process in order to have a chance to pass the stringent automotive-grade certification. Shanghai Luxin's single-tube product AU40N120T1 obtained AEC-Q101 certification in November 2019, and is currently undergoing automotive-grade certification for 650V and 1200V series products.

With advantages such as excellent product performance, high reliability and rapid market response, Shanghai Luxin products have been successfully introduced to many leading corporate customers in domestic subdivided industries. At present, Shanghai Luxin products have been widely used in charging piles, OBC, main drive, auxiliary drive, air conditioning compressor drive, PTC heater, etc. in the field of new energy vehicles, covering almost all power conversion products of new energy vehicles.
