Abstract
A bridgeless buck-boost power-factor-correction (PFC) rectifier with positive output voltage is proposed herein. This PFC rectifier operates in the discontinuous conduction mode (DCM). Owing to the DCM, a good performance on PF is easily achieved as well as no reverse recovery currents being generated from the diodes. By means of output voltage sensing along with the traditional voltage-follower control, a proper control force is created to drive the switches. By doing so, not only the output voltage is stably controlled at a given value, but also the input current tracks the input voltage as tightly as possible. In addition, the accompanying harmonic distortion meets the requirements of the IEC6100-3-2 Class C harmonics standard, and accordingly, the proposed rectifier is suitable for the AC-DC LED driver. Finally, via mathematical deductions and experimental results, the effectiveness of the proposed bridgeless buck-boost PFC rectifier is verified.
