Robust Control Design for Grid-Tied EV System with SOGI-Based Architecture in Wide Voltage Range Scenarios

The development of a 1-Φ, 2
^nd
-stage OBC (On-Board Charger) for low load might operate in (G2V) Grid to Vehicle operating modes is shown in this paper. For this objective, a 2
^nd
-Order Generalized Integrator control technique, that demonstrates a robust steady state and exceptional vibrant behavior, is used to govern the H-bridge inverter. An electric vehicle (EV) charger's 1
^st
-stage AC/DC converter plays a critical role in preserving the grid's power factor unity. to maintain the power quality PQ of the grid within the limits established by the IEC (International Electrotechnical Commission)-61 000-3-2 while it is in use. Additionally, several operating situations, including swell & sag grid voltage, and other factors have been used to confirm the design's performance. Buck-Bosst converters are employed in the second step of the process to convert DC to DC. To regulate the switches on the DC-DC converter, a proportional integral controller is used. The battery's charging current and voltage are monitored and managed using a PWM controller with a constant battery current. An detailed examination of simulation data is conducted for 1.3kWatts system rating. An extra inductive load is connected to grid in order to test its responsiveness.
