The irradiation effect of DC-DC power converter under x-ray
The irradiation response of DC-DC power converter was studied using X-ray source with whole and local irradiation method. It was indicated that the irradiation response of the different part of circuit was represented different effect. The VDMOSFET of DC-DC power converter was tremendous irradiation affected, and PWM and Shottky diode was exiguous affected, and the trend of DC-DC power converter optical-coupler parameters affected by optical-coupler was reversely with other part of DC-DC circuits.
Characteristic analysis of total dose irradiation annealing effect in SOI NMOSFET
The effect of total-dose irradiation annealing on SIMOX SOI MOSFET with different bias and temperature was studied. It has been demonstrated that the annealing effect was more remarkable with ON bias than the others and more obvious in high temperature than room temperature.
Ground Fault Protection for Electric Utility Generating Station Medium Voltage Auxiliary Power Systems
Most generating station designs have medium voltage auxiliary power systems with low resistance grounded neutrals.1 In order to provide even higher reliability, the auxiliary power distribution system configurations supply increasingly redundant process equipment.
