  3. INTRODUCTION • Unique solid state technology invented in 1995 • ScandiNova founded in 2001 • Installations in 24 countries • (North-South America, Europe, Asia, Australia) • Accumulated operational hours >500 000 • Use in 10 applications

  4. Product Portfolio

  5. OUR INVENTION Three principal concepts Split Core™ Parallel Switching™ Pulse to Pulse Control™ The inventors of the LCW modulator Mikael Lindholm, SE Walter Crewson, USA David K Woodburn, UK

  6. TECHNOLOGY • Split Core™ • Key component for • excellent performance • Advantages • Low primary voltage level • Enable parallel switching Split Core Modulator sc.paper

  7. TECHNOLOGY • Parallel Switching™™™ • Normal operation – sharing the load • Single switch fault – not critical • Advantages • Improved reliability • Enables better pulse control
