This work presents the positive output buck-boost (POBB) converter with single loop control and simple converter structure. The presented POBB converter achieves the square of the high step-down/step-up voltage conversion gain as compared with the traditional buck-boost (TBB) converter and also the output voltage polarity is positive. These advanced features facilitate work in a wider range of high-step-down/step-up positive output converters. In the high gain POBB converter the two controlled power switches are operated synchronously. The converter is designed to operate in continuous current mode (CCM), one in switch-on mode, during which the two inductors are energized and two capacitors are discharged, and the later one in switch-off mode, during which the two inductorsare deenergized and two capacitors are charged. The operating principles and the steady-state analysis of high step-don/ step-up POBB converter operating in CCM are presented in detail. Further, a closed loop voltage mode control (VMC) is designed and simulated to study the line and load regulations of POBB converter in both high step-down (buck mode) and high step-up (boost modes) respectively. Theoretical analysis and predictions of the closed loop VMC POBB converter have been validated using MATLAB/Simulink platform.
