Solution


In the current version the DC/DC-converter supplies an electrical power output of 120 kW. The microcontroller-based phase control ensures optimal adaptation to the current load via active phase management.


Result

The devices modular topology allows for customised performance classes. The concept enables seamless control of the converter from buck to boost. The active phase management ensures a consistently high degree of efficiency over the entire performance range. In the boost mode efficiency averages at 97%.
