The currently available systems to save the child are less effective and costly too. Thus the society is in need of a new technique which is more efficient and effective. In most cases reported so far, a parallel hole is dug and then horizontal path is made to reach the child. It is not only a time taking process, but also risky in various ways. The borewell rescue system is capable of moving inside the same borewell where the child has been trapped and performs various actions to save the child. CCTV camera is used to continuously monitor the child’s condition. This system has a high power LED which acts as a light source since light intensity inside the hole will be less. The advancement in the field of automation along with the mechanical design has a great impact on the society. This project includes series of process development from hand drawn sketches to computer generated design. The modern equipments are implemented for various parts of the system, since the system performs a life rescuing activity. The light weight servomotors are implemented for the system’s operations. Borewell rescue System is a human controlled computerized system embedded with additional safety devices.
目前可用的拯救儿童的系统效率较低,成本也较高。因此,社会需要一种更高效的新技术。到目前为止报道的大多数情况下,先挖一个平行的洞,然后再挖一条水平的路到达孩子身边。这不仅是一个耗时的过程,而且在各个方面都有风险。井内救援系统能够在孩子被困的井内移动,并执行各种行动来拯救孩子。闭路电视摄像机被用来持续监控孩子的状况。这个系统有一个高功率的LED作为光源,因为洞内的光强度会更小。随着自动化领域的发展,机械设计对社会产生了巨大的影响。这个项目包括从手绘草图到计算机生成设计的一系列过程开发。由于该系统执行救生活动,因此系统的各个部分都实现了现代化的设备。该系统的运行采用了轻型伺服电机。井下救援系统是一种人工控制的计算机化系统,嵌入了额外的安全装置。

THD Analysis of Cascaded Multi-level Inverters using different PWM Techniques 采用不同PWM技术的级联多电平逆变器的THD分析
Pub Date : 2019-06-30 DOI: 10.31142/IJTSRD23984

Multi-level inverters (MLI) are used in places or industries that require very high voltage and huge current. Multi-level inverter topologies have various advantages over single level converters. These advantages are like: rise in output voltage, reduction in the total harmonic distortion (THD), reduction in electro-magnetic interference (EMI) generation etc. Key attribute of a multi-level inverter is the reduction in the voltage stress on each power device. This reduction is due to the use of several levels available on the DC bus. The dawn of multi-level inverter
多级逆变器(MLI)用于需要非常高电压和大电流的场所或行业。与单电平变换器相比,多级逆变器拓扑结构具有多种优点。这些优点是:提高输出电压,减少总谐波失真(THD),减少电磁干扰(EMI)的产生等。多级逆变器的关键特性是降低各功率器件上的电压应力。这种减少是由于在直流总线上使用了几个可用的电平。多级逆变器的曙光
