“…The main criteria for designing a current stabilizer are: allowable overheating , allowable voltage drop U1, allowable stroke xm of the levitation winding, allowable ratio of the height of the windings (or magnetic circuit) to their thickness (or width of the magnetic circuit) and the accuracy of current stabilization for a given range of changes in mains voltage U = Umax -Umin. As a generalized model, the design of a stabilizer with maximum symmetry and homogeneity of the magnetic system is considered (Boldea, 2015) (Kurniawan et al, 2022).…”

The present article discusses the characteristic features of the characteristics of precision controlled high-precision current stabilizers using the effect of induction levitation. The stability and shape of the load current determines the reliability, accuracy, efficiency, service life of automation devices, test equipment and electroplating baths. Determining the output characteristics, establishing analytical relationships between the initial data and the output parameters of the stabilizer is one of the stages of the algorithm for solving the problems of designing the parameters of an AC stabilizer with induction levitation of the moving part. This, in turn, contributes to the development of a mathematical model consisting of a system of equations of electric, magnetic, mechanical and thermal stabilizer circuits, the joint solution of which allows you to establish analytical relationships between the initial data and parameters such as working stroke, weight, winding and core sections, copper losses

“…Uninterruptible power supply (UPS) is an electric power system that is able to provide power quickly when electronic devices need it, at the right time to avoid the effects of data loss [1]. One electronic device that is widely used and requires that it is always connected to a power supply is a computer [2], [3]. The continuity of the electricity source which is usually sourced from PLN to computer equipment cannot be relied upon because it is often interrupted and unstable, so uninterruptible power supply (UPS) is needed [3], [4].…”

Fully controlled rectifier and BCR. The battery charge regulator (BCR) is the most important unit of an uninterruptible power supply (UPS) device. The BCR uses a 15 V/5 A transformer to lower the voltage so as not to overload the BCR components. Full control using four thyristors serves to supply voltage to the BCR, while the BCR serves to regulate battery charging. Forcing the battery to be charged at a constant voltage with the same current results in shorter battery life. Battery charging through the BCR is set to match the battery voltage, then allowing the BCR to control it by adjusting the phase voltage to 13.5 V for high voltage discharge (HVD) and 10.5 V for low voltage discharge (LVD). By using an IC Regulator combined with a relay as a voltage breaker for a fully charged battery, it will automatically disconnect to avoid overcharging the battery. Based on the performance test results of a fully controlled rectifier system using thyristors and BCR on a 12V/5Ah battery, the output voltage is as a fully controlled 12 V rectifier, the BCR switch can charge the internal battery in minutes with a current that varies between 2.1 A to 0.1 A.

Considered as basic structures of next‐generation energy system, environment‐friendly and flexible microgrid (MG) systems are potential solutions to address integration issues of stochastic renewable energy sources. Adaptable energy management approaches provide the possibility to construct effective and various energy interaction. The purpose of this paper is to present a problem‐oriented review of energy management in MG systems. This paper first comprehensively reviews recent research studies on MG, particularly in multi‐microgrid (MMG). Then, this paper proposes a concept of energy utilization model for energy management, which includes a discussion of modern concepts including MG, MMG along with picogrid, nanogrid and virtual power plant. And a synthetic energy management framework including stability, touch, efficiency, evenness, and resilience dimensions is proposed and formulated based on energy utilization mode. Then energy management system is illustrated from the perspectives of system function, management architecture, operation logic and data analysis, and further, a systematic four‐layer hierarchical architecture of management systems for whole MG and MMG systems is proposed. Moreover, key technologies in energy management are summarized and reviewed from the aspects of control, communication, prediction, optimization, and evaluation. Last, eight main prospects on the future trend of energy management in MG and MMG are also presented.
