SOLID STATE TECHNOLOGY

Split Core
Reducing primary voltage levels brings many advantages, and this is what ScandiNova achieved with its split-core concept. The idea is as simple as it is beautiful. Simply split the core of the pulse transformer, once or multiple times. This lowers the primary voltage to a level suitable for commercially available switches. Furthermore, separating the control and actual high-voltage pulse environments from one another allows use of solid-state technology. Total pulse control is the result – a huge improvement over previous methods.
Even though Split Core™ technology was initially developed to increase personal safety and improve pulse reliability, our R&D team soon saw an even greater potential to achieve the perfect pulse; much improved control and performance, not to mention significantly decreased electrical power consumption and lower maintenance costs.
PARALLEL SWITCHING™ – SECURES RELIABILITY
A reliable pulse ensures better results. ScandiNova’s Split Core™ technology led to the development of Parallel Switching™, the concept that achieves just this. Reduced voltage levels permit the use of IGBT switches, thus avoiding the less reliable Thyratron or serial-coupled switch models. This enables a faster Time to Duty (TtD) for the pulse (the time until useful flatness is achieved). What’s more, IGBT switches generate a very clean pulse shape.
Years of testing in laboratories and in real production environments have proven that this concept works. The very first modulator ever built and delivered to Japan for use in an advanced radiotherapy system ran for almost 15 years without any service or maintenance. Not a single part was replaced!
Parallel Switching™ means stable operations, perfect duration and a pulse to rely on.
