Abstract: Poor power quality, moderate dynamic reaction, high gadget stretch, consonant rich, occasionally thick, peaky, mutilated info current are the significant issues which are every now and again experienced in traditional switched mode power supplies (SMPSs) utilized as a part of personal computers (PCs). To overcome these issues, it is proposed here to utilize a non-isolated bridgeless buck-support single ended primary inductance converter (SEPIC) in discontinuous conduction mode (DCM) at the front end of a SMPS. The bridgeless SEPIC at the front end gives solidly controlled output dc voltage even under successive information voltage and load varieties. The output of the front-end converter is connected with a half scaffold dc-dc converter for seclusion and furthermore to obtain distinctive dc voltage levels at the heap end that are required in a PC. Controlling a solitary output voltage can direct the various dc output voltages also
