摘要: A novel switching-frequency control method for regulated 1-switch boost rectifiers operating at the boundary of discontinuous and continuous conduction modes is presented in this paper. To obtain a source current with least amount low-order harmonics, duty cycle within switching period proportional to ratio instantaneous value voltage output voltage. According large signal analysis, can be by adjusting frequency. Small modelling performed facilitate design process. The proposed scheme features advantages such as higher input power factor compared traditional fixed frequency constant cycle. Any well-developed commercial PWM IC adopted only minor modification. Experimental results show good conformation theoretical analysis.
