Abstract

When conventional boost power factor corrector (PFC) circuit operates in high power application, rectifier bridge diode causes high power loss. A bridgeless PFC circuit with digital signal processor (DSP) control is implemented in this paper. Average current mode is implemented by DSP and the input current follows the input voltage. Therefore, the PFC converter achieves high power factor and low total harmonic distortion current. The operating principle of semi-boost PFC converter is analyzed and the parameters of key components are design. The software of average current mode control in DSP is described. Outer voltage loop, inner current loop and the design of the compensator are introduced. Finally, a 1.3 kw bridgeless PFC circuit with DSP control is implemented. Input voltage range is $90 V_{rms} ~ 264 V_{rms}$ and output voltage is constant 400 V. Maximum efficiency is 98.1%. Maximum power factor is 0.996 and minimum iTHD is 5.1%.
