Buck Converter in Closed LoopPIDPIPWMUPSInstabilityThis chapter discusses the closed-loop control of the open loop BUCK converter discussed in the earlier chapter. The closed-loop design is illustrated with the Simulink ® model and the corresponding waveforms for different control parameters of ...
In this paper, a wide range of adjustable single-stage Buck converter with rail-to-rail output characteristics is designed as a pre-regulator for the wide range of adjustable output high power supply. The closed-loop feedback compensation controller and software-configurable soft-start control ...
Finally, this quadratic buck converter was simulated with openloop and closed loop using MATLAB/Simulink. The results show that the power factor and the total harmonic distortion (THD) is good for closed loop Quadratic buck converter compared to the openloop Quadratic buck converter.R.Srikanth...

This paper gives the design and implementation of closed loop Buck/Boost converter for automobiles. This model operates in either charging or discharging mode. Both modes of operation are not possible at same time. Hence it forms a unidirectional adapter for the Buck/Boost converter. In charging ...
