| Abstract |
In this paper new topologies and interleaving modulation concepts for multilevel DC-DC boost converter enabling a significantly less loss and a reduced chip size of the power semiconductors are proposed. Moreover, a new soft switching concept is presented. The achievable efficiency, chip area and boost inductance reduction are compared with existing solutions for an input voltage of 800 V, an output voltage of 3 kV and an output power of 150 kW. A 30\% loss reduction and a chip area decrease by 50\% is achieved. |
