Company History


The Siebel Engineering Agency is established by Dr. Henrik Siebel to realise customer-specific developments in power electronics.


High insulation power supply units are developed in-house, and GvA Leistungselektronik in Mannheim takes over the distribution of these products.


For the production of these power supplies Dr. Henrik Siebel and Wolfgang Scholl set up Siebel & Scholl GmbH.


Siebel's long-standing collaboration with Frigoblock Gro├čkopf GmbH in the development and production of control components for refrigeration systems is established.


The four-channel GIS18-35AD power supply is developed in collaboration with ABB Switzerland. This device is optimised to also supply power semiconductors such as IGCTs and GTOs.


The inverter control unit and CAN IO module are added to the product range. With customised software they are designed for use in the range of more powerful converters.


The engineering agency extends its customer base with innovative developments for the automotive industry ranging from test bed components in motorsport right through to hybrid components for commercial vehicles.


International markets open up. Sun.King Group is appointed distributor for the Chinese market.


Wolfgang Scholl bows out of the company as Managing Partner.


Siebel & Scholl GmbH is renamed Siebel Elektronik GmbH, and new company premises are purchased jointly with the engineering agency. The equipment installed at the new building for research, development and production meets all the latest technology requirements.
