Abstract
This paper describes application of type-3 compensated error amplifier for switch-mode dc-dc converter using OrCad/Pspice simulation tool. For several decades power supply design has been showing a gradual movement away from the use of linear power supplies to the more practical switched mode power supply. The linear power supply contains a mains transformer and a dissipative series regulator that increase the size extremely and heavy 50/60 Hz transformers, and also very poor power conversion efficiencies approximated below 50%. These drawbacks are improved using switch mode power supplies that incorporates fast switching devices having estimated efficiency of above 80%, compact size and light in weight. These features are mainly due to the controller as a basic building block apart from the Dc-Dc converter, which is the heart of switch mode Dc power supply. Thus, in this paper application of type-3 compensated error amplifier for switch-mode dc-dc converter has been proposed and implemented using OrCAD/Pspice tool. Accordingly, dynamic and steady-state performance/evaluations have been performed for step changes input/output (load) side. The results revealed that the system has fast dynamic response and reduced steady-state error for input and output side disturbances.
