Abstract

In this paper, the current sensorless control for dual-boost half-bridge (DBHB) converter with power factor correction (PFC) function is presented. The short-through problem can be avoided by the dual-boost structure for enhancing the reliability. It also reduces the power dissipation due to the body diodes' reverse recovery current of switches. Furthermore, the intrinsic voltage-doubler characteristic of half-bridge structure is often used in high voltage application. The conventional multiloop control needs many voltage and current feedback signals. In order to simply the control loops and reduce the number of sensors, the feasibility of current sensorless control strategy should be evaluated. Therefore, the electrical characteristics of the proposed current sensorless control scheme are completely analyzed in this paper. At last, some simulation and experimental results are provided to demonstrate and illustrate the performance of the proposed current sensorless control.
