“…To test the effectiveness of the modular MPPT algorithm, a comparison has been made among the performances of MPPTs like P&O MPPT [11], adaptive P&O MPPT [12] and auto-tuned MPPT [13], and [1] implemented in the studied PV system. In Table 3, showing the differences between P&O, adaptive P&O, auto-tuned P&O, and self-tuned MPPTs.…”

“…The literature has reported on [9] various voltage boosting strategies in which simple energy storage elements (inductors and condensers) and/or transformers are used in the circuit in combination with switch (s) and diode (s). This paper proposes a [10], [11] noninverting buck-boost (NIBB) continuous-conduction mode (CCM) converter with a quick duty cycle calculation (FDCC) control and duty cycle locking technique. Nowadays the research is going in wide varieties of wireless sensor networks [12]- [19], embedded system [20]- [22], antennas with IoT applications [23]- [30].…”

“…The output voltage of the photovoltaic system is variable due to uncertainty in the radiances. However, to ensure a constant or controlled production voltage, DC-DC electronic power converters are used [6]- [11]. DC-DC converter based on green energy is becoming an increasingly attractive solution for these applications.…”

The establishment of the latest IoT systems available today such as smart cities, smart buildings, and smart homes and wireless sensor networks (WSNs) are let the main design restriction on the inadequate supply of battery power. Hence proposing a solar-based photovoltaic (PV) system which is designed DC-DC buck-boost converter with an improved modular maximum power point tracking (MPPT) algorithm. The output voltage depends on the inductor, capacitor values, metal oxide semiconductor field effect transistor (MOSFET) switching frequency, and duty cycle. This paper focuses on the design and simulation of min ripple current/voltage and improved efficiency at PV array output, to store DC power. The stored DC power will be used for smart IoT systems. From the simulation results, the current ripples are observed to be minimized from 0.062 A to 0.02 A maintaining the duty cycle at 61.09 for switching frequencies ranges from 300 kHz to 10 MHz at the input voltage 48 V and the output voltage in buck mode 24 V, boost mode 100 V by maintaining constant 99.7 efficiencies. The improvised approach is compared to various existed techniques. It is noticed that the results are more useful for the self-powered Embedded & Internet of Things systems.

“…The author wants to reduce the power consumption of the AM receiver circuit to the utmost limit and operate it with energy harvesting as the power source. There is a lot of research on energy harvesting [3][4][5][6][7], and our team is also researching on on-chip power generation [8]. If the AM receiver can be operated using the energy harvest as the power source, it will be convenient because power line and charging will not be required.…”

Wireless communication with AM (Amplitude Modulation) is widely used. If the power consumption of the AM receiver is reduced to the utmost limit, the power source can be replaced with an energy harvest, which is very convenient. Power lines will not be needed and batteries will no longer need to be replaced or recharged. Therefore, we propose an ultra-low power demodulation circuit for AM receivers. The proposed demodulator achieved a peak SNDR of 47.8 dB and a power consumption of 3.36 μW at a carrier frequency of 1 MHz.

Energy harvesting technologies are attracting attention because they remove power supply lines and charging. However, energy harvesting has many problems such as small power generation and instability, and low output voltage. As a step toward putting this attractive technology to practical use, I have developed a CMOS temperature sensor with on‐chip photovoltaic cells. The photovoltaic cells achieved an open circuit voltage of 0.97 V, a short‐circuit current of 8.0 μA, and a maximum power generation of 6.5 μW in an area of 800 μm square. Experiments have shown that the prototype CMOS temperature sensor can operate without external power supply. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
