Abstract

This paper presents a current sensorless control for dual-boost full-bridge (DBFB) converter with power factor correction (PFC) function. In this topology, the short-through problem can be avoided, and the freewheeling current flows through the independent diode rather than the body diodes of switches. Therefore, the reliability and availability can be improved. The proposed current sensorless control scheme only requires input and output voltages, and that is a simple control strategy without any current sensor. At first, the equivalent single-switch model of the dual-boost full-bridge PFC converter is analyzed and derived. In addition, the experimental control algorithm is implemented by using the DSP TMS320F28335 chip. Finally, some simulation and experimental results are given to validate the performance of the proposed current sensorless control method.
