| Abstract: | The interleaving technology can be used to obtain the output results of the higher switching frequency with lower switching frequency,ripple cancellation,current sharing between the phases.A control schematic based on the peak current control circuit was designed and its working principle was described after analyzing the basic principle of two-phase interleaving synchronous buck converter.Finally,the circuit modeling of LTspice and simulation waveforms were given,which proved the correctness of the control circuit. |
