Fuji Electric Co., Ltd. announces the release of V-Series Intelligent Power Modules (IPMs), which are fitted with Fuji Electric’s latest 6th-generation insulated gate bipolar transistor (IGBT) chips to greatly reduce power loss. 

Fuji Electric announced that it had developed the V-Series of 6th-generation IGBT chips in April 2010. With the development of the V-Series of IPMs fitted with the 6th-generation IGBT chips, the Company is moving ahead with a series of sales releases as detailed in the chart below. 

The V-Series IPMs achieve the industry’s lowest level of power loss and radiation noise, made possible by the 6th-generation IGBT chips along with Fuji Electric’s latest drive integrated circuit (IC)※. By maximizing the modules’ low-loss properties, Fuji Electric was able to reduce their size and thinness by as much as 80% of that of conventional models. 

With these low-power-loss and compact features, V-Series IPMs can contribute significantly to reducing size and energy while raising efficiency in various applications of power electronics, including general-purpose invertors, numerical control machinery, industrial robots, business-use air conditioners, and power conditioners for photovoltaic power generation. 

※ The drive IC controls the on/off switching of IGBT modules and provides protective functions.

1. Product features 

(1) Fuji Electric’s latest 6th-generation IGBT chips and most recent drive IC enable the modules to achieve the industry’s least amount of power loss (20% lower than Fuji Electric’s previous products) and lowest level of noise 

(2) Modules are fitted with four alarm lights as an output function for signaling causes of abnormalities—an industry first 

(3) Overall size and thinness of the modules have been reduced by as much as 80% compared to conventional products
