First, the operation principle of boost PFC with TCM control is described. The continuous time-domain model of boost PFC with TCM control is established by state space average method. A DSP platform for digital-controlled boost PFC based upon TCM control is set up. A family of predictive current controlled methods adapted to digital pulse-width modulations is presented. The switching period time of the proposed control is predicted by parameters of converter and sampled inductor current which is sampled by ADC with low sampling frequency in order to achieve zero current switching. Therefore, neither zero-current detector nor high-frequency A/D converter for current sampling is required for the proposed control method. Moreover, a digital-controlled predictive current with master-slave technique for interleaved PFC with TCM control is proposed. And a new on-time compensation technique is proposed to significantly improve the slave inductor current distortion and thereby achieving current sharing control between phases. Finally, an on-line parameter tuning technique for predictive current mode control is proposed to deal with the issues of discontinuous current mode (DCM) operation and larger current ripple which are caused by parameter variation in predictive current mode control. The proposed method gives one more current sample in one sampling period in order to estimate the inductance of boost inductor on line and thereby tuning the parameter of the predicted switching period. Experimental results demonstrate the effectiveness of the proposed control method for digital-controlled boost PFC with TCM control. 賴炎生 2013 學位論文 ; thesis 108 en_US |
