This paper introduces a single-bridge current source rectifier, which eliminates 5th and 7th harmonics adopting the technology of Selective Harmonic Elimination(SHE).
介绍了一种单桥电流源型整流器,运用特定谐波消除技术消除其5次和7次谐波。
It can also serve as a bridge between current manual testing processes and future test automation.
它也可以作为当前的手工测试过程和未来的测试自动化之间的一座桥梁。
For example, in Roman times, engineers discovered that if the upstream supports of a bridge were shaped to offer little resistance to the current of a stream or river, they would last longer.
例如,在罗马时代,工程师们发现如果桥的上游的桥墩建成对目前河流水阻力小的形状,桥墩的寿命会更长。
