This paper presents the Dual In-line Package Intelligent Power Module (DIPIPMTM) family that dedicated for Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) air-conditioner inverter drive applications. The DIPIPMTM product family that targeted for automotive applications adopted the advanced CSTBTTM power chip technology and embedded in to Mitsubishi Electric’s unique insulation-sheet type transfer mold package that is capable to provide the excellent electrical characteristics and superior reliability for automotive application. By using the optimized wafer and assembly process, the DIPIPMTM achieved a package size that small enough to be able to dramatically shrink the compressor mounting space. Examples of DIPIPMTM in air-conditioner inverter drive application for electric vehicle that targeted for long drive range and heavy passenger load are introduced.

Nowadays, High efficiency for power electric conversion is more and more important. With higher efficiency, you can reduce the loss of power devices, have more compact design, and save system cost. One way is to use expensive SIC components, the other is to use much cheaper Si-based IGBT with multi-level topologies. This article will introduce IGBT-5 based power modules to have high efficiency but with reasonable cost.

To pursue a lower system cost and a higher power generation efficiency, sola power industry is heading to the direction of 1500VDC system. As key devices for the system, solar inverters must be able to handle the DC input voltage as high as 1500V, and have a power capacity above 1MW which is expected by the inverter manufactures for power density and cost reasons. This paper presents the performance of new designed split NPC 3L modules together with a built up inverter solution that is designed dedicatedly to meet the new demand of 1500VDC solar inverters. By splitting the NPC 3L topology into top and bottom parts, a powerful built up 3L leg can be achieved, which has 1200V blocking voltage and 1200A chip current. The switching characteristics of each IGBT and diode are measured on a built up 3L inverter by using the well-known double pulse test method. Furthermore, the inverter is tested with full power on a back to back inverter test bench. Testing and simulation results verify that the split NPC 3L inverter is capable to output 750A RMS current at 5kHZ switching frequency with and efficiency of 98.7%, which means more that 750kW output power at 600VCA without module paralleling and 1.5MW with 2 pairs of modules in parallel. Compared with the traditional 3 half bridge modules build up solution, the introduced split NPC 3L solution has one less module and much easier bus bar design, which can lead to a compact and cost effective inverter design.
