With the aim of providing designer guidelines for choosing the most suitable solution, according to the given design specifications, in this paper a review of charge pump (CP) topologies for the power management of Internet of Things (IoT) nodes is presented. Power management of IoT nodes represents a challenging task, especially when the output of the energy harvester is in the order of few hundreds of millivolts. In these applications, the power management section can be profitably implemented, exploiting CPs. Indeed, presently, many different CP topologies have been presented in literature. Finally, a data-driven comparison is also provided, allowing for quantitative insight into the state-of-the-art of integrated CPs.

Transient Overvoltage

The development of smart power systems in Industry 4.0 will bring people better quality electrical energy. The photovoltaic power generation system in the smart grid for Industry 4.0 is also the focus of development. The rapid development of photovoltaic power generation systems will bring people cleaner and greener energy. However, it will cause the transient overvoltage phenomenon near the DC sending terminal when the large-scale photovoltaic plant is connected to the power grid, further bringing about a profound impact on the power grid and its security and stability. In this paper, it is proposed that the rise of transient overvoltage at the photovoltaic terminal is caused by three main factors including the reactive power surplus of DC commutation failure, the weak power grid at the sending terminal, and the control characteristics of the photovoltaic plant. Then, the coordinated control strategy of transient overvoltage is proposed, and the overvoltage control strategy of the DC transmission terminal and the photovoltaic power plant control strategy are, respectively, optimized. Finally, the influence parameters of overvoltage are analysed and the corresponding photovoltaic strategy is presented. The optimization results of photovoltaic parameters and the proposed strategies of photovoltaic power generation can effectively restrain the voltage or frequency fluctuation and power oscillation caused by HVDC commutation failure. This study promotes the development of the photovoltaic power generation system in the intelligent power system of industry 4.0.

Ring Core

A novel electromagnetic energy harvester (EMEH) based on double-ring core for power line energy harvesting is proposed in this paper. Due to large magnetic reluctance caused by the inherent air gap at the opening of core, the magnetic flux leakage in magnetic core severely limits the output power of EMEH. A double-ring core with lower magnetic flux leakage is developed. The internal magnetic reluctance of the double-ring core is reduced by changing the distribution of the air gap with a fixed volume. The simulation results show that the double-ring core can produce the highest average magnetic induction, which is 2.42 times, 1.82 times and 1.7 times that of the single-ring opening, stepped opening and V-shaped opening, respectively. In order to improve the output performance of the EMEH, the resonance matching is used for the power management. The power management unit through the resonant matching can increase the acquisition efficiency by 2.23 times and achieve a maximum output power of 32.78[Formula: see text]mW at a 10[Formula: see text]A current across the power line. The EMEH can drive a low-power wireless node operating for 29[Formula: see text]min. A valuable solution is provided for high-efficiency self-powered systems in smart applications.
