The control strategy applied to a novel Boost converter composed of coupled inductor is proposed,and the aver-age model of main circuit is presented,with the help of which,the control to output transfer function is given,and based on which the compensated regulator can be designed easily.This circuit can be used in small and middle level uninter-rupted power supply (UPS) to boost the lower battery bank voltage in order to supply the inverter.Hence,the bulk of UPS is smaller.Finally,the simulative and experimental waveforms verify the correctness of the analysis.
