ABSTRAK Sumber energi listrik PLN merupakan sumber utama bagi masyarakat. Namun kenyataan saat ini masih belum maksimal dalam menyalurkan seperti dapat terjadi pemadaman, dan fluktuasi tegangan yang gangguan AC. Gangguan sendiri menyebabkan kerusakan pada beban rumah tangga. Oleh karena itu, jurnal membuat suatu inovasi dengan memanfaatkan dari Baterai berfungsi untuk membackup ketika mengalami...

The paper aims to analyze the parameters of prototypes new overvoltage protection devices for power grids—a multi-chamber insulator arrester (MCA) and a long flashover (LFA). article presents research results on determining actual MCA LFA impact characteristics. Moreover, were compared assess effectiveness devices. presented in this will supplement missing information about They make it possibl...

Abstract Benefitted from progress on the large-diameter Ga 2 O 3 wafers and processing techniques, power device technology has witnessed fast advances toward electronics applications. Recently, reports large-area (ampere-class) devices have emerged globally, scope of these works gone well beyond bare-die demonstration into packaging, circuit testing, ruggedness evaluation. These results placed ...

Single-ended (SE) resonant inverters are widely used as power converters for high-pressure rice cooker induction, with 1200 V insulated-gate bipolar transistors (IGBTs) being switching devices kW-class products. When voltage fluctuations occur at the input stage of an SE inverter, applied to IGBT can be directly affected, potentially exceeding breakdown IGBT, resulting in its failure. Consequen...

With the development of 1500 V photovoltaic (PV) systems in recent decades, multilevel inverters such as five-level inverter have gained much attention for their higher equivalent output frequency and low semiconductor devices’ voltage stress. Among inverters, active neutral-point-clamped (ANPC-5L) is very competitive due to its simple structure control methods. However, with conventional commu...

A carbon nanotube [CNT]/Co3O4 composite is introduced as a catalyst for the air electrode of lithium-air [Li/air] batteries. Co3O4 nanoparticles are successfully attached to the sidewall of the CNT by a hydrothermal method. A high discharge capacity and a low overvoltage indicate that the CNT/Co3O4 composite is a very promising catalyst for the air electrode of Li/air batteries.

The high penetration of photovoltaic (PV) systems and fast communications networks increase the potential for PV inverters to support stability performance microgrids. in distribution network can work cooperatively follow centralized decentralized control commands optimize energy production while meeting grid code requirements. However, there are older autonomous that have already been installe...

We present the ferroresonance overvoltage mitigation concerning power systems of grid-connected wind energy conversion (WECSs). WECS is considered based on a doubly-fed induction generator (DFIG). Ferroreso-nance associated with single-pole outage line breaker mitigated by fast regulating reactive using static compensator (STATCOM). STATCOM controller introduced, in which two incorporated propo...

This work is devoted to the calculation of the undulatory parameters and the study of the influence of te number parallel path of a winding on overvoltage compared to the frame and between turns (sections) in a multiturn random winding of an asynchronous motors supplied with PWMconverters.
