capacitortransformerAs the pulse power supply in electron linear accelerator,the line-type pulse modulator is used to produce the high voltage pulse which come into being when the pulse forming net(PFN)is discharged.The frequency and stability is related to the PFN charging system.The breakthrough...
A strobe charging device includes a light-emitting tube; a main capacitor for accumulating energy and for supplying the energy to the light-emitting tube; a transformer circuit which includes primary and secondary coils in order to accumulate the energy of a power supply in the main capacitor; ...
Inverter with pre-charging capacitor to reduce inr 优质文献 相似文献 参考文献 引证文献A simple DC-link pre-charging method for three-phase voltage source inverters Besides inrush current, pre-charging of the DC-link capacitor is one of the most important, since too low voltage may cause the ...
A constant current high voltage power supply for charging the capacitor with variable switch frequency is described.Full-bridge series resonant topology and intelligent power modules(IPM) are used,and the switch frequency is controlled by the feedback signal of the resonant current to keep the chargi...
The invention relates to a method for determining the operating state of electrical power storage means consisting of at least one ultracapacitor. When charging said electrical power storage means, the invention involves: measuring the v... CINNERI, Patrice - EP 被引量: 4发表: 0年 The Analysis...
A capacitor charging power supply incorporating a series-parallel load-resonant power converter, operating at resonance at a fixed frequency and providing a constant load current, is presented. A series-parallel load-resonant power converter containing three resonant components is shown to have three re...
Charging a supercapacitor through a standard resistance can take a long time due to the RC time constant. The constant current converter will raise the voltage continuously as the capacitor is filled, until the highest charge voltage is obtained without overshooting the maximum set voltage. ...
The leakage current36 proves to be an unsuitable criterion for assessing aging during long charging to the nominal voltage. Moreover, the leakage current falls steadily over time, which makes it difficult to determine a defined value. The continuous self-discharge, U/U0 ∼ lg t, in Fig. 8...
The frequency-dependent capacitance of the graphene nanosheet capacitor shows that the capacitance value was 175 μF and the RC time constant was less than 200 ms at 120 Hz (Fig. 2c). Moreover, some graphene-based electrode materials prepared using the CVD method have been used to increase ...
which resulted in an average discharging time of 23 s and charging time of 363 s for Moving bed 1 (seeTable 1).Fig. 4shows the current density of the replicate moving bed bioanodes, which were operated for 67 days. The current density is normalized to the volume of granules in the dis...
