Voltage sag is one of the most severe power quality disturbances to be dealt with by industrial sector, as it can cause process disruptions and results in substantial economic loss. A short-term decreasein voltage lasting anywhere from milliseconds up a few seconds called sag. At present, wide range very flexible controllers, which capitalize on newly available electronics components, are emerg...

A novel ZVZCS isolated dual series-resonant active-clamp dc–dc converter is proposed to obtain high efficiency. The proposed converter employs an active-clamp technique, while a series-resonant scheme controls the output voltage with the complementary pulse width modulation controller. The active-clamp circuit serves to recycle the energy stored in the leakage inductance or the magnetizing ...

A substrate-triggered technique is proposed to improve ESD protection efficiency of the stacked-NMOS device in the mixed-voltage I/O circuit. The substrate-triggered technique can further lower the trigger voltage of the stacked-NMOS device to ensure effective ESD protection for the mixed-voltage I/O circuit. The proposed ESD protection circuit with the substrate-triggered technique for 2.5V/3....

A New electrical method, using charge-pumping (CP) technique under bias thermal stress (BTS), has been described in this paper. This technique is based on the charge-pumping measurement which in turn used to extract the flat-band voltage before and after an applied bias voltage at high temperature. The obtained flat band voltage shift, that is due to redistribution of the mobile ionic charges, ...

Space Vector Modulation (SVM) Technique has become the most popular and important PWM technique for three phase Voltage Source Inverters. Z-Source Inverters have the ability to boost the dc link voltage, thus increasing the output ac voltage beyond the values reached by conventional inverters. The enhanced ratio from ac output voltage to dc link voltage is possible due to an impedance network c...

n-channel power vertical double-diffused metal-oxide-semiconductor field-effect-transistor (VDMOSFET) devices were subjected to a high electric field stress or to a x-ray radiation. The current-voltage and capacitance-voltage measurements show that the channel-side interface and the drain-side interface are affected differently in the case of high electric field stress, whereas the interfaces a...

The Multi-voltage technique is an effective way to reduce power consumption. In the proposed cell-based voltage domain programmable (VDP) technique, the high and low voltages applied to logic gates are programmable. The flexible voltage domain reassignment allows the chip performance and power consumption to be dynamically adjusted. In the proposed technique, the power switches possess the feat...
