脉冲阻塞
A small projection through which grease in a grease gun can be forced into a bearing. The paper mainly researches the magnetized mechanism of the strong magnetism to injected water, and the augmented injection implements used pulse blocking is designed.
滑油嘴一个小的突起,通过它滑油枪中的润滑油能被注入轴承着重研究了强磁对注入水的磁化机理,同时设计强磁增注器,实现脉冲解堵。
On idle, using the voltage-feedback control makes PWM modulator output the pulse disjointedly with blocking-oscillation frequency lowered and the pulse width narrowed. Accordingly not only the no-load loss is less, but also the transformer is not easy to saturate.
系统在空载时由于采用电压反馈控制使PWM调制器间断地输出脉冲,间歇振荡的频率低而脉冲宽度窄,不但空载损耗小,而且使变压器不易饱和;
