Abstract:

The voltage distribution along the non-linear resistance of metal oxide surges is of great importance for their proper operation, since the non-uniform potential distribution results in higher thermal stresses of the varistor discs near the high voltage electrode, leading to a faster ageing of the discs at the top and, consequently, a downgrade in arrester effectiveness and reliability or even failures. The current work deals with the examination of the voltage distribution along the non-linear resistance of medium voltage metal oxide gapless surge arresters, using an appropriate computer tool

Abstract:

The AlGaN/GaN materials with a wide band gap, high electron mobility, and high breakdown voltage are suitable for manufacturing high-power and high-frequency electronic devices. In this study, metal Schottky contact electrodes of different dimensions are prepared on AlGaN/GaN wafers to fabricate metal–semiconductor–metal (MSM) varactors. Voltage-dependent capacitance and breakdown voltages of the varactors are measured and studied. The corresponding breakdown mechanisms of varactors with different electrode gaps are proposed.

In the conventional SiC-MOSFET, a PN junction diode is included between the source and drain. This P-N junction diode not only causes device degradation, but also generates a large reverse recovery surge voltage during high temperature operation. This surge voltage increases the electrical stress of the power converter, causing dielectric breakdown and control malfunction. We have developed a SBD integrated SiC-MOSFET. This MOSFET reduces the occurrence of reverse recovery surge voltage during high-temperature operation caused by inactivating the included PN junction diode. In this paper, we d

Abstract:

The problem of circuit breaking becomes complicated when voltages and currents in the range of kilovolt and kiloampere are involved. Circuit breaker (CB) is used in performing switching operations, and is a switch that can open live circuits. Circuit breakers are especially important in protective schemes where they have to interrupt fault currents, and isolate faulty section of the network. When the circuit breaker opens under fault condition many thousands of amperes pass through the contacts and the extinction of the arc and hence effective opening of the contacts of the CB are major engine

Metal oxide surge arrestors (MOSA) are commonly used in the electrical power system to protect the insulation from the damaging effect of lightning. This paper presents the damage characteristics and possible root cause of two exploded ZnO type arrestors. Both failures were not caused by lightning surge. They had degraded due to moisture ingress, leading to contamination and corrosion, accelerating thermal runaway effect in the ZnO elements and eventually caused early voltage breakdown under normal operating voltage. This indicated an inadequacy in the sealing components.

Abstract:

Zener voltages of the fabricated SiC Zener diodes with various nitrogen concentrations in the range from 7×1017 to 5×1019 cm-3 are 17 to 87 V, and decreased with an increase in the nitrogen concentration. Furthermore, in a chopper circuit using SiC Zener diodes for SiCGT gate protection, the commutated current decreases slowly even though cathode current falls rapidly, and the SiCGT gate is protected from surge voltage by SiC Zener diode. Moreover, the value of Zener voltage after the operation was the same as that before half bridge operation at 47 V.

Abstract:

<p class="IEEEAbtract">A novel design and simulation results of 9-steps automatic AC voltage regulator based on one step-down transformer is presented in this paper. Avoiding the problem of surge at the AC load during controlling jump steps is done through the proposed design. Accurate and smooth controlling function is achieved as well. Instead of the necessity of increasing the number of taps of the used multi tap transformer for wide controlling range of fluctuated AC supply voltage, the proposed designed adopts using only two step down transformers with 10 Vrms, and 30 Vrms secondary
