| Popis: | 99 An interleaved pluse-width modulation (PWM) converter with Boundary Conduction Mode (BCM) bridgeless buck-boost power factor corrector (PFC) is presented to achieve input power factor correction, current harmonic reduction and reactive power compensation. By using interleaved technique, the current stress of the semiconductor devices and the ripple currents on the input and output sides are reduced. Besides, the switching losses of the switching components are also reduced by employing BCM control. The advantages of the proposed converter are, high-efficiency, high power factor and low output current ripple. Finally, the operation principle, design consideration and simulation results are discussed in detail. The proposed BCM bridgeless buck-boost high power factor corrector and a single-stage high power factor buck converter are verified by the experimental result. |
