**6. Discussion**

A MatLab/Simulink model is simulated using the small-signal model derived in Section 3 along with the control strategy presented in Figure 10, where the parameter mismatch presented in Table 4 is introduced to the employed modules.

As can be observed from Figure 11, the control strategy for the proposed eight-module hybrid converter can accomplish the requirements. Results, presented in Figure 11, demonstrate that the controller in Figure 10 compensates for the negative influences resulting from the system parameters mismatch. In which the modular input voltages and the modular output currents are equally shared between the four modules. It can be seen from the presented results in Figure 11 that the primary multimodule group is in charge of delivering 4 5 of the total desired power while the secondary multimodule group is in charge of delivering 1 5 of the total desired power. Besides, the output current of the proposed power converter tracks the reference current that relies on the burp charging algorithm. Accordingly, it can be concluded that the applied control strategy is reliable and that equal power-sharing is achieved between the employed modules.
