Transient Response Improvement of Buck Converter
Sliding mode (SM) and Proportional-integral-derivative (PID) controller are implemented for Buck converter in a continuous conduction mode. A closed-loop controller system is implemented and goes through the transient time response of buck converter. Sliding mode controller is worked as robust controller and can be used to reduce the Delay time and settling time of the system. In power drives c...
متن کاملFuzzy Logic Controller for Fast Transient Response DC-DC Converter
Keywords: DC-DC buck converter, Fast transient response, Fuzzy logic controller (FLC). A new low output voltage and fast transient response dc-dc converter is designed in order to feed devices such as microprocessors and DSPs. It is a fast response DC-DC buck converter (FRBC) comprising of two buck converters connected in shunt and controlled by Fuzzy logic controller. First the Linear Control ...
متن کاملUse of state trajectory prediction in hysteresis control for achieving fast transient response of the buck converter
A dynamic hysteresis control of the buck converter for achieving high slew-rate response to disturbances is proposed. The hysteresis band is derived from the output capacitor current that predicts the output voltage magnitude after a hypothesized switching action. Four switching criteria are formulated to dictate the state of the main switch. The output voltage can revert to the steady state in...
متن کاملTransient Response Improvement of DC-DC Buck Converter With Adjustable Sawtooth Signal
Transient response performance is very important in DC-DC converters. It measures how steady the output voltage is maintained when the load changes suddenly. For single inductor dual output (SIDO) converters (1)~(4) that work in continuous conduction mode (CCM), the transient response affects cross-regulation: if the load of one sub-converter changes, the output voltage of the other sub-convert...
متن کاملControlling of Fast dynamic DC/DC Buck Converter
This paper presents, linear peak current mode controller for the control of DC/DC buck converter is designed and analyzed. Dynamic equations describing the buck converter are derived and linear peak current mode controller is designed. The buck converter, the voltage mode and current mode controller are modeled and are evaluated by computer simulations. The proposed technique has the advantages...
