“…However, due to utilization of PV in applications such as car mounted PV and wearable technology (backpack PV), the systems could be subjected to very rapid irradiance change, that is, up to 100 W/m 2 /ms. 36 For that reason, the MPPT performance is tested under very fast irradiance change, that is, step waveform. In this test, the initial G is set to 300 W/m 2 .…”

The direct and indirect control methods are commonly used for maximum power point tracker (MPPT) of photovoltaic (PV) systems. Due to the absence of the literature that assess their performance in a comprehensive way, this work attempts to analyze the effectiveness of both control methods for the perturb and observe (P&O) MPPT algorithm. The MATLAB/Simulink simulation is verified experimentally using a PV array simulator and the dSPACE DS1104 DSP board driving a buck-boost converter. The results show that the indirect method exhibits lower steady-state oscillation and is less sensitive to rapid irradiance change and load variations. It increases the steady-state efficiency by 1.6%. Furthermore, under irradiance and load step changes, the transient efficiency increases by 29% and 30%, respectively. Based on these findings, it is envisaged that the indirect method is more suitable to be used as the controller in conjunction with the MPPT algorithm.

“…Also, the proposed UFD is applied successfully for fault-tolerant operation of a buck/buck-boost two-stage converter with synchronous control and a redundant switch. Photovoltaic (PV) energy is also one of the most popular DC renewable energy sources for an energy harvesting system with a compound annual growth rate of 42% from 2000 to 2015 [7]. PV energy has been used recently in some applications, such as manned [8,9] and unmanned vehicles [10,11] and wearable technology [12,13].Due to the intermittent and unregulated nature of the previously discussed energy resources (TEG and PV), Maximum Power Point Tracking (MPPT) algorithms must be employed to maximize the power transfer from the source to the load.…”

“…Moreover, in many applications, the output voltage level of the energy harvesting system must be controlled and adapted to the load voltage. The best choices to apply these algorithms (and control), undoubtedly are two-stage DC-DC converters [7,[14][15][16].Thus, different types of DC-DC converters have an important role in renewable energy resources and energy harvesting applications. Generally, there are two different categories of DC-DC converters: Isolated and non-isolated.…”

This paper proposes a new Unified Switch Fault Diagnosis (UFD) approach for two-stage non-isolated DC-DC converters used in energy harvesting applications. The proposed UFD is compared with a switch fault diagnosis consisting of two separate fault detection algorithms, working in parallel for each converter. The proposed UFD is simpler than the two parallel fault diagnosis methods in realization. Moreover, it can detect both types of switch failures, open circuit and short circuit switch faults. It can also be used for any two-stage non-isolated DC-DC converters based on two single switch converters, no matter the converter circuits in each stage. Some selected simulation and Hardware-in-the-Loop (HIL) experimentation results confirm the validity and efficiency of the proposed UFD. Also, the proposed UFD is applied successfully for fault-tolerant operation of a buck/buck–boost two-stage converter with synchronous control and a redundant switch.

Today, energy harvesting has developed into a technique from which various aspects are still hidden. By extracting energies from the environment and even the human body, and converting them into electrical energy, we can supply power to low‐consumption electronic devices. Energy harvesting works by inhibiting small amounts of ambient energies; otherwise, it is wasted in other forms such as heat, vibration, and light. In this paper, we aim to eliminate or minimize the dependence of portable electronic devices to the batteries, which have limited life times, service costs, handling, and environmental problems. This is accomplished via incorporating the hybrid energy‐harvesting techniques and designed to power (bio)medical devices in order to measure vital signs. In this circuit, by simultaneously harvesting RF, light, thermal, and solar (natural and artificial) energies, we were able to increase the reliability of continuous supply of electrical energy in energy‐harvesting systems by generating and storing maximum power from the environment. Supercapacitors are used as the energy storage elements so that there is no energy waste, and each system is constantly storing the electrical energy with the aid of a diode block. In addition, with the help of supercapacitors, this device is able to transmit a maximum of 420 mW to the load and the total efficiency is equal to 74%.
