Abstract：
 The parallel connection interleaving operational method of the power factor corrector in the critical and consecutive conducting mode belongs to the field of the control technology of the power converter. It chooses the method of digital dead beat control, adopts single DSP, confirms one of the several shunt-wound BCM Boost convertors as the master convertor, which is controlled in closed loop, and the rest as the appurtenant convertors, which are controlled in open loop. Under the condition of variable switch frequency and sampling frequency, make the inductive current of the appurtenant convertors follow the inductive current of the master convertors and realize the parallel connection interleaving operation of the BCM Boost APFC convertor. It only samples the input voltage and the output voltage, does not need to detect the peak value of the switched current in the hardware or to judge the crossover point of the inductive current, can get relatively high power and control it more simply.
