The thesis proposes the design and implementation of a fully digitally controlled full-bridge converter with power factor correction. The converter includes two major parts: a power factor correction circuit and a full bridge DC/DC converter. The zero switching technique is used to reduce the switching loss of the DC/DC converter. In addition, a single-stage power factor correction circuit is implemented to improve the power factor in the input AC source.
The detailed discussion and analysis are included. An adjustable dead-time control method is proposed here. A 768W, 48V converter has been implemented. All the control algorithms are implemented by a digital signal processor. The experimental results validate the correctness of the proposed circuit, which has good performance and meets the PFC standards.
