使有效

Referenced to the CSR's trilogic PWM signal generation, an approach to achieve lowstress natural commutation of switching devices by reshuffling the vector composition sequence, resulting reduced switching loss. With the background of and well instanced by the Xinjiang Autonomous Region's Key SciTech Project"Solar Photovoltaic grid-connected inverter", the dissertation work implemented the new approach of a grid-connected PV inverter that was of single-phase VSR topology and with MPPT .

在研究了两类电网不平衡时的VSR控制策略基础上，提出了一种新型的基于无阻尼振荡控制器的VSR不平衡控制策略，在简化控制结构的同时，有效地改善了电网不平衡时的VSR控制性能；通过二、三值逻辑开关函数间的转换，系统地描述了三相CSR三值逻辑PWM信号发生中的状态切换；结合三相CSR三值逻辑PWM信号发生规律，提出了通过调整矢量合成顺序而使功率管获得自然换相的低电压应力SVPWM控制，从而有效地降低了功率管的开关损耗。

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。
