In this report a novel high efficiency topology has been proposed,
which is using low voltage switches and manage
bidirectional power flow in 700V applications.
A methodology has been established to perform analytic
calculations of power losses.
A thermal model in Plecs has been created to predict the
As the result, the simulation confirms the analytical calculations,
the worst case efficiency is 97% at 3 kW in boost
mode and 98:3% in buck mode.
The converter has been designed and built. Due to time
constraint the verification of high efficiency is postponed to
after the report submit.
