Over the decades, with the advancement of science and technology, wheelchairs have undergone remarkable changes, such as controlling an electrical wheelchair by using brain signals. However, existing electrical wheelchairs still need improvements in terms of energy management. This paper proposes an hybrid Solar-Radio frequency (RF) harvesting system able to supply power for the continuous and effective operation of electrically powered wheelchairs. This system can simultaneously harvest power from RF and solar source that are both available in the surrounding environment. A maximum power point tracking (MPPT) and a boost converter are exclusively employed for the standalone solar system while the standalone RF system is equipped with a 9-stage voltage multiplier (VM). The voltage level for the charging process is obtained by adding the output voltage of each source. In addition, a current booster and a stabilizer are used to reach the required level of current and pin the charging voltage to a stable level, respectively. Simulation results show how the hybrid system is better and more stable when the boost current and stabilizer are used in the charging system. Moreover, we also provide some analytic results to prove the advantages of this system.

“…It is widely known in the literature that conventional BC is inadequate for high-gain requests due to the parasitic circuit resistance and the limited commuting periods of semiconductor components. These drawbacks can limit the converter gain, where the output voltage value will not exceed twice the input voltage [2], [3]. Furthermore, some applications, such as converters designed for renewable energy and light-emitting diode (LED) drivers, should be supplied with a constant current from the DC source [4].…”

This paper suggests a new method to achieve input current ripple (ICR) reduction of the quadratic boost converter (QBC). The planned converter is represented by adding an auxiliary inductor connected in a series with the bootstrapping diode to a QBC. The benefit of this arrangement is to implement the interleaving concept to lessen ICR, while the quadratic concept is to attain the voltage gain within the required level. However, this modification will slightly affect the output voltage; the effect depends on two factors: the duty cycle and the auxiliary inductor value. The performance improvement includes increasing dynamic response speed, reducing reverse recovery and conduction losses in semiconductor devices and less oscillation observed by ICr, leading to better stability than the conventional converter. Therefore, the converter's overall efficiency is improved. A comparison with a typical QBC was presented using the LTspice program to demonstrate the improvement.

The main purpose of this paper is to obtain optimum power from a Photovoltaic (PV) panel and deliver it to a load system under standard irradiance and temperature weather conditions. Standard Boost DC-DC converters and bidirectional Buck-Boost DC-DC converters work as voltage controlling units for the power provided from the PV panel, which is used to charge the battery and supply suitable voltage signal to AC load. MPPT technique, based on two control algorithms, Particle swarm optimization (PSO) and Incremental Conductance (INC), is used to extract maximum power from the solar cells. Matlab/ Simulink environment is adopted to simulate the proposed PV power system. Simulation results are presented and analyzed based on transient and steady-state performance parameters. The performance results of the PV array system under the Standard Test Conditions (STC) showed that the INC-MPPT control algorithm can provide a
