Functional Power Module Technology: Providing Power Modules Perfectly
Matched to The Specification

We develop highly efficient, highly functional power modules for inverters,
converters etc., using our unique power circuit and in-car mounting technology
along with our own power semiconductors. In particular, we adapt our semiconductors
to the specifications of the final product to attain superior efficiency, miniaturization
and weight savings.
The functional power modules we develop use many of power semiconductors of
our own manufacture, such as diodes, thyristors, and MOSFETs. We also utilize
our unique circuit technology in single phase and 3-phase bridges, etc., to
help heighten the efficiency of products. With the power semiconductors we
install ranging widely from tens to 600 V and tens to 100 A, synergy with our
semiconductor business is one of the strengths of our products. With many years
of accomplishments in in-car mounting technology, we develop and supply products
of high quality. Also, we select the mounting substrate materials best suited
for the output current, application, etc., and have a ready system to respond
flexibly to custom specifications by incorporating predrivers, etc.


The construction of functional power modules fit to the unit
| 1) |
Single-phase/3-phase bridges |
| |
Power semiconductors of our own manufacture installed, such as diodes, thyristors, and MOSFETs |
| 2) |
Predrivers |
| |
Power semiconductor predrivers can be installed. Some common kinds of predrivers, for illustration, include non-insulating-type bootstrap systems, suitable for synchronous rectification, and floating systems. |
| 3) |
Applications |
| |
A broad range of markets are supported, including industrial devices and the automotive market. |

The functional power modules we develop are poised for great success in motor
control installed in ecological cars like HEVs and EVs.
