Electronic R&D

Electronic and control R&D

Innovation in power electronics is vital to provide a wide range of generators from our own production and technology and with control and communications functions and performances covering every customer’s needs in the different industries.

All the research and development work of GH GROUP is done at the R&D department of GH ELECTROTERMIA, S.A.U.

The R&D department has, amongst many others, the patent for the first transistor generator designed for its application in induction heating. It also has lengthy experience in designing resonant converters, with series and parallel technology, as well as in the use of MOSFET and IGBT transistors. The R&D department has established 75 cooperation contracts with different universities and research centres and goes on with these cooperation schemes year by year.

To sum up the R&D work done by the Department, some of the points deserving mention are that it has undertaken 87 projects since 1986, 45 of which have been given public financing; it has attended international conferences on 60 occasions and 94 papers have been presented at congresses.

The most important recent events to be stressed are that in 2007 the R&D Department of GH Electrotermia was awarded the first Prize in the Avanza Plan in the PROFIT category (best tractor project) by the Ministry of Industry, Tourism and Trade (MITYC) for its project entitled: “Processing and optimisation of quality and cycle time improvement in production of parts with complex geometry in the automobile sector by means of a multi-frequency induction heating system”.

The Electronic R&D department has had its own functional organic structure since 1985, when it was set up.
