在设计中，以TL 494作为PWM产生电路输出控制信号，控制开关管的导通状况，在半桥反激式输出的基础上实现了电源的多路输出。
In the design, to produce circuit TL494 as a PWM output control signals, control of the on-switch situation, the half-bridge flyback output on the basis of the power of multi-output.
在我们的情况下，晶体管的关闭和变压器模式工作在反激。
In our case the transistor turns off and the transformer operates in flyback mode.
其结果表明，管跨的同向涡激振动一般不会对管线系统的正常运行构成威胁，而管跨的横向共振则必须予以消除。
The results show that in line vibration can not bring serious danger to submarine pipeline system in most cases, while cross flow vibration must be eliminated.
