pull current造句
例句与造句
- in the diagram, the output of the error amp is connected to the base of an npn transistor : when the error amp drives current into this transistor's base, it allows current to flow from collector to emitter, and that transistor in turn pulls current from the base of the pass transistor
在这个图里，误差放大器的输出端连接到了一个npn三极管的基极上：当误差放大器输出电流到了三极管的基极上，三极管允许电流从集电极向发射极流动，这个传输三极管工作时就是就是从基极吸取电流的过程。 - push-pull current mode hfl inverter also is composed of four power switches . the simulation and experiment of a 500va experimental prototype indicates that this circuit has the advantages of less components, simple topology, the ability of four quadrant operation and high efficiency . the inverter does not need the symmetry of the components " parameters and can be applied to dc to ac conversion with single low input voltage source
推挽双向电流源高频链逆变电路也是由四个功率管组成，500va的原理样机的仿真和实验研究结果表明，该电路元器件少、电路拓扑简单、能够四象限可靠运行、变换效率高，并不要求器件参数的完全对称，适合于输入电压较低的场合。 - particular way is : it is plan tax basis with commodity sale, the tax rate consideration that provides according to tax law gives commodity to answer the appreciation the amount of tax to be paid of the burden, deduct next goods and materials is bought outside be being used to produce commodity place cost ( wait like raw material, fuel, running stores ) before pull current understands link already the value added tax of pay, the remaining sum after deducting is an enterprise to answer ratal
具体做法是：以商品销售额为计税依据，按照税法规定的税率计算出商品应负担的增值税额，然后扣除为生产商品所耗用外购物资（如原材料、燃料、低值易耗品等）在以前生产流通环节已缴纳的增值税，扣除后的余额为企业应纳税额。 - from the view point of the whole topologies of current mode hfl inverters, two topologies of half-bridge and push-pull current mode hfl inverters are proposed, which are composed of four power switches . hfl inverters in discontinuous current mode ( dcm ) are extended to those in continuous current mode ( ccm )
从完善电路拓扑和降低成本的角度出发，本文提出了两种结构的电流源高频链逆变电路，它们分别是由四个功率管组成的半桥和推挽双向电流源高频链单级逆变电路，并将工作在电感电流断续模式的逆变电路扩展到电感电流连续模式。 - It's difficult to find pull current in a sentence. 用pull current造句挺难的
