Currently, the front-end of DPS is realized by a highly customized design with multiple outputs using the PWM converter technologies These topologies suffer significantly, with poor efficiency due to hold-up time requirements. The prototype demonstrated at CPES represents significant improvement in both efficiency and power density. This particular topology no longer suffers due to hold-up time requirements. Companies such as Intel, IBM, and HP are pushing the change of distributed power architecture to a much more simplified approach using basic building blocks like what is described above. It is anticipated that this approach will be adopted in the near future.
