The objective of this thesis is to develop a DSP-based single-phase boost converter with power factor correction.

中文摘要本文的目的是研制一个数位信号处理器控制之1 kW的单相升压式功率因数修正器。

This paper is based on the research and development of single phase active power factor corrector and high quality power module.

本文以单相有源功率因数校正控制器和高性能功率模块的研制、开发为依托，对其从理论和应用开发两个方面进行了较为全面的研究和讨论。

XRD analyses indicated that both as-cast and melt-spun alloys were of the CaCu5-type structure single phase, but the crystallizability and composition homogeneity of the melt-spun alloys were improved.

XRD分析表明，铸态和快凝合金均为单相CaCu5型结构，但快凝合金的成分和结构均匀性得到明显改善，并具有较低的吸氢体积膨胀率。

But also may carry on related "the daylight lamp electric circuit" and "enhancesthe power factor" with "the single phase AC electric circuit" the experiment.

还可以进行与"单相交流电路"有关的"日光灯电路"和"提高功率因数"的实验。

At last, the growth mechanism selection of the decagonal quasicrystal was also achieved by means of changing the structure of the nucleation substrate, which provides the direct experimental evidence for the theoretical research of quasicrystal.

且当熔体过冷度大于临界值时，单相准晶生长将发生从侧向生长向连续生长的粗糙化转变，最后通过改变触发形核衬底结构类型实现了连续和侧向两种生长机制的自由选择。

Single Al-Ni-Co decagonal quasicrystal particles were prepared by the combination use of conventional casting and ball milling. The coated Al-Ni-Co quasicrystalline particles were prepared by sol-gel processing.

采用常规铸造法和球磨法制备得到单相Al-Ni-Co十次准晶颗粒，并采用溶胶－凝胶法在准晶颗粒表面成功的添加了涂层。

Thus, the coefficients of governing equations are pressure dependent and consequently the analysis of transients in the two-component flows is more complex and difficult than in single-component flows.

而且，控制方程的系数是与压力相关的，因此在含有两种物质瞬变流动分析比单相流动更为复杂和困难。

Derate current rating by 50% for single phase AC input.

单相AC输入降低50％额定电流。

This paper is mainly about research and design on charger, discharger and single phase PWM rectifier of this scheme.

本文主要对课题方案中的充电模块、放电模块、单相PWM整流器进行了研究设计。

Because it has structure in brief and circulates credibility, maintenance convenience, the efficiency higher etc. characteristics, is usually used the small scaled breeze machine and water in the metals slice pare the tool machine, heavily the conveyance the machine, to pump etc. become produce a machine equipments in, single dissimilitude's treading electrical engineering 恻 an application is more in the experiment with the home appliances product.

因为它具有结构简单、运行可靠、维护方便、效率较高等特点，通常被用在金属切削机床、起重运输机械、中小型风机和水泵等成产机械设备中，单相异步电机恻在实验和家用电器产品中应用较多。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
