| 摘 要： | 主要讨论开关稳压电源的并联设计与制作，此电源具有功耗小，效率高，输出电流稳定以及输出功率大等优点，是大功率电器的理想电源。设计的是半桥式稳压电源，采用TL494集成块作为控制器，先用TL494集成块脉宽调制控制主电路的输出电路的输出电压保持不变，然后对主从电路输出进行采样，同时输入给高精度比较器，再用另一个TL494集成块脉宽调制控制这个比较器的输出结果，来调节从电路的输出电压，使主从电路的输出电压相等，产生80V、200W的输出。然后将两个这样的电源通过比较控制后关联起来，得到大功率（400W）的稳压电源。 |
| 关 键 词： | 并联输出 TL494集成块 高功率 脉冲宽度调制 |

| Abstract: | The text mainly investigated the parallel design and fabrication of the switch supply with high power. It is found that the switch supply has the advantages such as low consumption and high efficient in energy sources, and high power for output. It is an ideal supply to electric equipment with high power output. The ircuit with half- bridge steady voltage was used TL494 as the controller. Then we paralleled it with another one through being compared and controlled to get 400W power output. |
| Keywords: | Parallel opertation TL494 High power Ppulse- width modulation |
