| description | The deep concern towards clean and environmentally friendly energy has brought to the development of renewable energy-based systems such as energy storage systems and smart grids. Therefore, the isolation features and high energy management efficiency are essential in those applications, thus sparking the need for the isolated bidirectional DCDC converter. The dual-active bridge (DAB) DC-DC converter has gained attention due to galvanic isolation, high efficiency and promising high power density. This thesis presents the development of a 20kW DAB DC-DC converter using MATLAB/SIMULINK software. The DAB system is operated at 20kHz switching frequency with single phase-shift (SPS) modulation. The DAB performance during forward and reverse direction for various phase-shift angles is analyzed in DAB open loop system. Then, the PI controller is employed in the DAB system by using ZieglerNichols (ZN) for tuning the KP and KI parameters. The DAB with PI controller was tested for variation of loads, step-change of loads, step-change of desired output voltage and step-change of input voltage by analyzing the dynamic performance in terms of settling time, rise time and overshoot percentage. The system shows the fastest response when the load is changed from 10kW to 5kW at 200V with 0.04s during forward direction. While, with 0.03s, the system produces the fastest response when the load is changed from 10kW to 5kW at 450 V during reverse direction. In conclusion, the DAB system with PI controller is capable to produce a high dynamic response in the tested circumstances. |
