High power passive soft switched interleaved boost converters

The present project was developed in order to find a high power (/spl ges/5 kW), high efficiency step-up converter which could be used as a battery discharge regulator. Efficiency should be higher than 97%, mass should be lower than 2.5 kg, no galvanic isolation was required and MTBF should be as large as possible. Taking into account all these parameters our proposed solution has been two interleaved boost converters with passive soft switching.
