Rb is an electric locomotive operated by Swedish State Railways (Swedish: Statens Järnvägar, SJ). Six locomotives were built by ASEA, in three series designated Rb1, Rb2 or Rb3. During the 1950s SJ saw the need for a new universal locomotive, since the D-series was aging. In 1955 the Ra-series had proved successful with bogie wheels.

RB是由瑞典州铁路公司（瑞典： StatensJärnvägar，SJ ）操作的电力机车。 ASEA制造了六个机车，分为三个系列RB1 ， RB2或RB3 。 历史. 在1950年代，由于D系列正在衰老，因此SJ看到了新的通用机车。

2017年5月29日 · In this paper, we investigate the performance of the three-phase ac-ac matrix converter (MC) utilizing the novel superjunction (SJ) reverse-blocking (RB)-insulated gate bipolar transistor (IGBT) as switch elements for the first time.

通过较高掺杂浓度 N 柱、P 柱的相互耗尽和电荷补偿作用，超结（SJ）结构打破了单一载流子器件的“硅极限”，在较短的漂移区长度下可实现高耐压，被誉为“功率 MOS 的里程碑”，已在功率 MOSFET 领域获得了极大的成功 。 具有超结漂移区的超结 IGBT 结合了 FS-IGBT 和超结的优点，可实现高的耐压和低的损耗，为 IGBT 性能的进一步提升提供了新的思路。 然而，作为一种双极型器件，超结 IGBT 具有与超结 MOSFET 不一样的结构特点和工作原理，本文从超结原理出 …
