Abstract: DC-DC converter makes vital contribution in the field of effective power supplies for regulation of ripple free voltage with high quality. This paper presents an effective Lag controller design in frequency domain for dc-dc Buck Boost converter. Steady state analysis of high-power buck-boost converter is done in order to draw the control mechanism needed for its faithful operation by time- average model. The proposed control scheme is implemented with buck boost converter in MATLAB SIMULINK platform to verify the theoretical concept. Lastly a comparison is made between the closed loop and open loop response of buck-boost converter.
