In this paper the relative difference between stabilizing curve for Proportional Integral Derivative controller and Generalized Proportional Integral controller on transient and dynamic performances are discussed. It is observed that the Generalized Proportional Integral controller provides a good stabilization than the Proportional Integral Derivative controller in terms of delay time, rise time, peak time, settling time, and maximum peak over shoot and steady state error. This shows a greater degree of robustness in terms of disturbance rejection represented by severe changes in static and dynamic loads.Index Terms-Buck converter, integral reconstructor, , Proportional Integral Derivative (PID) control systems.
This paper describes buck converter with closed loop discrete Proportional, Integral and Derivative (PID) controller is designed and simulated. The dynamic performance of the buck converter can be improved by the design of discrete PID PWM controller. Analog PI & PID Controller of buck converter is designed and simulated whose performance parameters are compared with the Discrete PID Controller is illustrated. The DC-DC converter can withstand its regulation performance with the variations in input supply voltage, circuit inductance, capacitance and load resistance.
There are two proposed methods in this paper, one is two port BDC (bidirectional dc-dc converter) while the other is three port BDC. Both converters work on the principle of bidirectional power flow while the three port BDC under soft-switching condition. The DAB (Dual active bridge) which acts as an interface between energy storage devices (Battery or Ultra-capacitor) and electrical power network. Multi-winding transformer is used for galvanic isolation between source & load. The circuit uses phase-shift control of three active bridges connected through a threewinding transformer and a network of inductors .The circuit has been simulated using MATLAB Simulink. Simulation results are verified.Keywords-DC---DC converter, dual active bridge (DAB), three-port bidirectional DC-DC converter, zero-voltage switching (ZVS).I.
