“…The DRM is a simple control strategy that uses the transient response of the TEGE to determine the operating point. This control strategy is adopted from the common control strategy used in the PV emulator [15], [16]. The Io is measured and fed into the TEG model, as shown in Figure 4.…”

“…Maintaining the continuous current mode hinges on the precise choice of inductance, L. Based on the conventional buck converter design, the L required to maintain the continuous current mode is shown in (15). The output voltage ripple is maintained by choosing the right capacitance, C. Based on the conventional buck converter design, the C required to maintain the output voltage ripple is shown in (16).…”

“…Consequently, to ensure proper design of the PI controller, it is imperative to maintain continuous current mode in the buck converter consistently. This is done by a proper design of L using (15). The continuous current mode operation in the simulation is observed using the minimum inductor current, IL(min), which never goes to zero.…”

Thermoelectric generator (TEG) can directly convert heat energy into electrical energy. It improves the power efficiency of the energy generation system by converting the power loss in the form of heat produced during the generation process into additional electrical energy. The TEG emulator (TEGE) is a power converter that produces a similar current-voltage characteristic as the TEG. It is a valuable device used to develop and test the TEG-based energy generation system. Nonetheless, the research on the TEGE is still in the early stage. This paper proposed a proper, low-cost, and high-efficient TEGE design using the buck converter. The contribution of the paper covers the TEG model in the form of an array, the buck converter design tailored to the TEGE, and 4 new control strategies proposed for the TEGE. The control strategies are the direct referencing method (DRM), perturb and observed (PnO) method, resistance comparison method (RCM), and resistance feedback method (RFM). The conventional proportional-integral controller is used to maintain a smooth operation during transient and steady-state periods. The results show the merits or demerits for each proposed control strategy based on the accuracy, transient response, stability, overshoot, and efficiency.
