| 摘 要： | 笔者设计了一款稳压电源，它由CW7812扩流而成，其突出优点是：输出电流大，能够满足大电流输出要求；输出过流时能够自动保护，可靠性高；负载调整率低，带载能力强；制作简单，使用电子元件少等优点。 |
| 关 键 词： | 过流 自动保护 扩流 电源 |
Design of a power supply with the expansion of CW7812 and overcurret automatic protection |
|
| Abstract: | The author designed a regulated power supply, expanded by the CW7812, its outstanding advantages is the high current output requirements can be realized and the output overcurrent can be automatic protection, high reliability and with low load regulation, strong carrying capacity, simple production, less electronic components. |
| Keywords: | overcurrent automatic protection expand current power supply |
