Power Conversion

VONK is your specialist when it comes to Power Conversion. With our expert knowledge and extended experience as our foundation, we endeavour at all times to rise to the challenges of tomorrow. Current developments in the field of energy transition play an important role in this. We are helping our customers realize their ambitions and goals. Learn more about how we can help you with drive systems, special converters, consultancy and projects.

Drive Systems

For over 50 years we have been active in the development of custom drive solutions for electrical motors and rotation systems. Using our state-of-the-art VONK Control Platform we can provide tailor-made solutions which are best in class when it comes to controllability, precision and harmonic distortion.

We have developed the first centrifuge drives for uranium enrichment application and today our customers represent half of the global enriched uranium production. Based on our thorough application knowledge, we are able to provide our customers with the best possible solutions for optimizing energy consumption and operational control. Our added value is a competitive advantage to our customers.

In the defense industry we have decades of experience with motor drives for radar applications which are both at sea and land based. Throughout the years we have developed our solutions to have best in class control accuracy and as little as possible harmonic interference with the complex electronics of the radar systems. This ensures that our customers can have the best functioning systems available.

Special Converters

Ever since we have enabled CERN to switch from transistor based power electronics to thyristor technologies in the 1970’s, we are an internationally recognized leader in the field of customised power conversion solutions for scientific institutes. Our track record with scientific industries is unrivalled with a long list of power supplies being delivered to institutes all over Europe.

For their research activities the scientific institutes we work with require facilities that go above-and-beyond. Whether it is a particle accelerator, a magnet laboratory or fusion physics installation, all institutes are pushing the envelope and this reflects in their power conversion demands. By working with these institutes for many years we have developed a range of different solutions, fitted for each application. This gives us the knowledge on which technology to use for which application, as we have seen it all and actually have done it all.

We continue to build upon our experience to create the best fitting solution for new applications that require special power conversion solutions. As we can use existing concepts and our state-of-the-art Control Platform, we can create custom solutions with the short lead times, pricing and limited risks of standard solutions.

Projects

”We believe in long-term relationships”

Predictable project implementation on the basis of incremental technological innovations and long years of experience. We believe in long-term relationships, so our projects endeavour at all times to find the best solution for our customers. These solutions come with low development risks, creating an optimum balance between the critical success factors of clients. This is reinforced by technological innovations which are constantly being developed and improved on the basis of proven technologies. In turn, we put these into practice in commercial projects. In this way, the customer can deploy state-of-the-art technologies without being unnecessarily exposed to development risks. Current technological developments include:

  • Digitally controlled semiconductor Active Front End (AFE IGBT) technology;
  • Low power DC/DC converters;
  • Universal firmware-controlled digital control platform;
  • Scalable Thyristor converters;
  • Active harmonic distortion reduction filters.

In the projects for our customers, in general, we use existing technologies and existing components as much as possible. This may involve the use of subsystems and/or components which have been developed in-house VONK Intellectual Property and/or which are commercially available. Projects based on existing technologies we call System Integration projects. Good examples of these include:

  • Integration of drive systems and converters within the processing industry, including digital control cabinets and installations;
  • Integration of customer-specific magnet power supplies in scientific institutes;
  • Upgrading and replacement of outdated (analogue) control systems and PLC operating systems;
  • Replacement of outdated drive systems.

In System Integration projects we combine technical know-how and project management skills with application know-how, so that hardware and possibly software can be integrated as part of an turnkey solution for the end user. Typical activities within the scope of System Integration projects are:

  • Project & Site management;
  • Interface simulations and (lab) testing with dummy loads;
  • System installation and testing;
  • Integration, verification and qualification;
  • Operationalization and release of systems;
  • Compilation of handover documentation;
  • System design;
  • Integration of existing building blocks (pre-existing IP);
  • Component selection and purchasing;
  • Maintenance manuals and planning;
  • (D)FMEA and MTBF analysis;
  • Inventory of required spare parts and management;
  • Commissioning and testing.

Projects which use new technologies have a different risk profile and so require a different approach. These projects are called Product Development projects. We perform these projects to develop our own building blocks and/or subsystems which can then be deployed in system integration projects. We can also develop customer-specific solutions, often in collaboration with other technology companies. Good examples of these include:

  • Drive system product development projects for powering electric motors and rotary systems in a maritime environment and the processing industry;
  • Special cooling systems for power applications in the maritime environment;
  • Power (AC/DC) converters and power lines for a range of magnet application projects;
  • Special power supply for oil-water separation systems.

In Product Development projects, we frequently use engineered components to develop newly required technologies such as our own building blocks or for customer-specific solutions. Typical activities within the scope of Product Development projects are:

  • Project management;
  • Risk management;
  • Engineering;
  • Functional design versus Critical to Quality customer requirements.;
  • Detailed design specifications, documentation, (standard) component choice versus standards, requirements, manufacturability and minimum costs;
  • Project purchasing, work planning and prototype assembly;
  • Acceptance (type) testing and qualification of the design:
    • Functional testing;
    • Power performance testing
  • Product industrialization;
  • Product documentation for the product, including manuals;
  • Integration of existing building blocks (pre-existing IP);
  • Multidisciplinary engineering services;
  • Design for X;
  • (D)FMEA and MTBF analysis;
  • Product qualification and certification.
