| Abstract: | A multi-outputs converter topology applicable for portable instruments is put forward. Non-isolated positive and negative voltage multi-outputs are achieved by using only one inductor. Cross regulation of the converter is studied and the technique which can reduce the influence of cross regulation is presented based on introducing the operating principle and control technique. Two derived topologies which can improve the performance of the converter are brought out. Key principles of the paper are verified by Pspice and Matlab simulations |
