Inverter Prototype

Here’s a detailed explanation of the installation methods and the specific benefits.

■Developed background of reference design

In recent years, demand for power semiconductors, key devices for contributing to realize a decarbonized has been rapidly expanding, in order to reduce developed workload in customer side, Mitsubishi Electric starts to provide data about prototype inverter composed with 3-paralleled industrial IGBT module in LV100 package: a standard size of "100mm×140mm", which have become popular for high-capacity inverter systems. The reference data will include design data, such as geometry, component layout and electrical circuitry, as well as evaluation data such as temperatures, short-circuit protection, current balance and computer-aided engineering (CAE) validation results.

■Prototype inverter components list and design information will reduce design workload

・The service will provide a list of components for Mitsubishi Electric’s proprietary prototype inverter and design information covering parts configuration, electrical circuitry, etc., helping to reduce the burden of parts selection and design.

・This module is widely used as a standard package for power semiconductor modules in high-capacity inverter systems, so information provided by the service will contribute to the design of inverter systems using the same package for other applications.

■Prototype inverter validation data reduces design, manufacture and evaluation workloads

・Validation data based on CAE analysis and evaluation data on temperatures, short-circuit protection, current balance, surge voltage, etc. for power modules, which tend to be burdensome when developing high-capacity inverter systems, helps to reduce design, manufacture and validation workloads.

・The reference validation data will also contribute to design and manufacture accuracy for prototypes developed according to each customer's design standards.

■Engineer's voice

The realization of GX is highly dependent on improving the power conversion efficiency of power electronics devices. The design to maximize the performance of the power devices, which are at the core of this, requires advanced technical skills and a long development period. With the provision of the prototype inverter we propose this time, we will also provide know-how, hoping to significantly shorten the development period and maximize performance, contributing not only to solving our customers' management issues but also to solving social issues. As a developer, I majored in electrical engineering at university and graduate school and obtained a doctorate. With that expertise, I have been designing and analyzing, and even considering heat dissipation. I imagine there are many improvements to be made in terms of structure and assembly, but please use it as a reference.
