目前市场上的大多数电热毯的加热方式都是全波加热，虽然可以通过档位控制加热温度，但在加热中需要手动换挡，使用较长时间后，会出现温度过高，影响睡眠质量的缺点。为了克服这一缺点，设计了基于555定时器的半波加热电热毯开关，这一开关的核心元件是以555定时器构成的多谐振荡器和半波镇流器。测试结果表明，这款开关不但有助于减少人们因温度不适需要调节而带来的麻烦，更有利于节约能源。

Generally, the heating method of electric blanket in the market is full-wave heating, and the heating temperature is controlled with different gears.It need shift the switch manually, which results in the tem-perature too high after a long time using which may reduce the sleep quality.To overcome this disadvantage, a half-wave heating electric blanket switch was designed based on 555 timer.The key elements in this switch are the multivibrator based on 555 timer and half wave ballast.The test result shows that the design can not only re-duce the shift trouble caused by discomfort coming from too high temperature, but also can save energy.
