Overview: New Intelligent Power Modules (R Series)
Atsushi Yamaguchi Hiroaki Ichikawa 1. Introduction
The equipment of power electronics application is prised of general use inverters, numeric control (NC) machine tools, and industrial robots. Recently, the requirements of lower noise, higher efficiency, advanced functions, lower price, and downsizing for these items have been growing. The power devices used as the equipment of power electronics applications are progressing toward lower loss and higher frequency, and the IGBT (insulated gate bipolar transistor) rather than the bipolar transistor is gaining popularity. On the other hand, together with lowered loss for the IGBT, intelligence is achieved by locating the peripheral circuits such as the driving circuit and various protective circuits inside the module. It then bees possible to shorten the design time at the power circuit and contributes to downsizing and advanced equipment function. In keeping step with the trends of making the power devices intelligent, Fuji Electric announced the bipolar transistor type of intelligent power modules

In 1992, the J series of IGBT-IPM (J-IPM) that pursued lower loss was developed and in 1995 the N series of IGBT-IPM (N-IPM) aimed at lower price and lower noise was developed and produced. This time, the R series of IGBT-IPM (R-IPM) pursues higher cost performance, higher reliability and advanced functions.
