Application of Harnessing Harmful Gas with Boost Technique;

Compared with the conventional HF link inverter or the DC/AC inverter with a Boost DC/DC stage, the efficiency is improved a lot, while the cost does not increase.

Based on this definition, it is easier to understand that in the linear modulation range to obtain a higher output line-line AC voltage, a kind of boost circuit should be inserted between the DC source and the three-phase inverter.

With the increasing number of switched capacitor cells,the topology of n-stage step-up resonant switched capacitor converter(RSC) is more complex,so it is hard to observe sneak circuit paths in the converter.

The step-up resonant switched capacitor (RSC) converter and the inverting RSC converter are studied in the paper.

Comparing to step-down resonant switched capacitor(RSC) converter,the composing principle of step-up RSC converter is different,so their sneak circuit conditions are not same.

Duration of Induced Hypertension on Cerebral Ischemia Reperfusion Injury in Rats;

Protective effect of mild hypothermia and hypertension on focal cerebral ischemia;

The working states of each executor of the braking pressure adjuster while routine braking,keeping,reducing and raising pressure are also introduced.

These kinds of power supplies can perform step down, step up and voltage inverting, which are very convenient and useful.

The gas electricity generation,pressure-rise,incorporation equipment necessary,can display the power set fully the characteristic,meets the mine pit power supply network safety work requirement.
