This joint S2B collaboration is focussed on the design, development and engineering of an innovative Integrated Power Electronic Matrix Converter (IPEMC) for driving high power permanent magnet brushless motors. The key inventive step involves the elimination of all of the bulky inductors that conventionally are used to shape the new AC wave form, using a novel inverter and control topology. It is a key enabling technology for the Downhole Gas Compressor (DGC) application where the machine must operate in an extremely small space envelope in a hostile environment. By being able to locate the DGC down hole and pressure boost close to the reservoir, large increases in rates of production (in range 28-42%) are achievable as well as significant increases in Ultimate Recovery (UR). This unique project results in significant miniaturisation of the power electronics for all industrial applications, while also increasing high temperature performance and ruggedness and reducing EM radiation.

此次S2 B联合合作的重点是设计、开发和工程设计用于驱动大功率永磁无刷电机的创新型集成电力电子矩阵变换器（IPEMC）。关键的创造性步骤包括使用新颖的逆变器和控制拓扑消除所有传统上用于塑造新AC波形的笨重电感器。它是井下气体压缩机（DGC）应用的关键技术，在这种应用中，机器必须在恶劣环境中的极小空间内运行。通过能够将DGC定位在井下并在储层附近增压，可以实现产量的大幅增加（范围为28-42%）以及最终采收率（UR）的显著增加。这一独特的项目为所有工业应用的电力电子设备带来了显著的性能提升，同时还提高了高温性能和耐用性，并减少了电磁辐射。
