A bidirectional converter is necessary for power transfer between two different voltage levels. This paper describes the implementation of the combined conventional buck and boost converter as the bidirectional converter, using the fuzzy logic controller as the control algorithm. The intrinsic diode of the MOSFET is used when the MOSFET is not in conduction mode, these diodes work as a conventional diode in each power conversion mode. The synchronous switching mode for both MOSFETs reduces the power losses during the switching due to the low RDS of the MOSFET over conventional diodes. Analyzing the parasitic resistance for both passive and active components helps optimize the component’s parasitic parameters to obtain optimal efficiency. The design of the fuzzy logic controller consists of fuzzy rules with the Mamdani inference system and membership function parameter tuning to achieve the best performance on low overshoot and fast transient response. The fuzzy logic controller is designed as a single controller to be compatible with both power conversion directions. The optimized design of only 8 fuzzy rules proved to be efficient for a fast microcontroller runtime with a robust transient response. The bidirectional converter can achieve up to 96% efficiency for the buck mode of 290W and 91% efficiency for the boost mode of 260W.

: This research was conducted to verify the significance of the LCL-filter on the grid current and the impact of variable fault resistance values on the reactive power genereated in a grid-tied inverter. The stability of LCL-type grid connected inverter with capacitor current feedback in active damping state was evaluated in this paper. The effects of balanced and unbalanced grid faults on the active and reactive power was studied through simulation at different fault resistance values of 0.00025Ω and 2.5Ω. The FFT waveforms showed that THD values of 48.56% and 38.45% were achieved for the grid voltage at 0.00025Ω and 2.5Ω fault resistance while THD values of 9.50% and 4.41% were obtained for the grid current at a varied current feedback coefficient (K CP ) of 4.75 and 14.75. Simulation results also showed that a very negligible real and reactive power was gained with a zero grid voltage within the fault zone at 0.00025Ω fault resistance. At a 2.5Ω fault resistance, a voltage sag was produced which accounted for the transient response in the real power generated and reactive power absorbed during the fault period. The result obtained from the root-locus plot showed that the loci for the derived LCL-filter current transfer function intersected at +j 8.734 and -j 8.734 which makes the system marginally stable All simulation procedures were realized in MATLAB/SIMULINK 2015.

: Ensuring a long battery life and satisfactory performance requires accurate charging cycles. There are three phases to the charge cycle - Constant Current Charge, Constant Voltage Charge, and Float Charge. It is usual that lead acid battery users complain about fast degrading performance because most the low cost commercially available lead Acid Battery chargers provides only single-stage charging phase which is that of constant-voltage charging phase. To ensure long service life and good performance, it is of paramount importance that all charging modes are respected. This said it is clear that the battery charger should have a certain degree of controllability over voltage and current quantities through-out the charging process. In this paper, we designed and built a lead acid battery charger to use in conjunction with a synchronous buck converter topology. After implementing and testing the system, we obtained good results in both the quantitative and qualitative analysis of the implemented system tested, a 12 V-7000mAh battery. With the help of a MCU-based digital control system containing two different control transfer functions - constant current Feedback Control and Constant Voltage Feedback Control monitoring the charging process proved possible without any overshoot. The prototype showed us an efficiency rating of 86.60%, the maximum error level was recorded at 0.05V, and there were no problems related to overshoot or transient response when testing our prototype which worked flawlessly.
