Abstract
In this paper two DC/DC boost converter topologies: isolated half-bridge DC/DC boost converter and current-fed push-pull DC/DC boost converter were compared. Both converters are designed to meet the demand for high efficiency and high voltage gain in low input voltage and high current applications such as renewable energy systems. The comparison has been made taking into consideration the efficiency, voltage gain and range of changes of duty cycle. In order to verify theoretical assumptions and principle of operation two prototypes were designed and compared in the same working conditions. Converters achieved efficiencies over 94% and voltage gain greater than 8.
