Abstract :
The half bridge DC-DC topology with current doubler rectification is suitable for high current low voltage applications. In this paper, both analog and digital unified state space models and small signal models valid for symmetric, asymmetric and duty cycle shifted controlled half bridge DC-DC converter are derived. The discretized analog model and derived digital model are compared based on the digital controller design. In addition, a digital controller is designed based on the digital model for symmetric half bridge DC-DC converter. The results are verified by experiment.
