电视机在农村已相当普及,一些偏僻农村,电压常常不稳、偏低,有的地区晚上电压仅160V左右。这样,就使电视图象扭动,甚至无法收看。为解决这一问题,向大家推荐一个实用35W交流稳压电路,如图所示:元件选择:R_1,20kΩ、2W线绕电阻;R_2,150kΩ、1/2W金属膜电阻;C_1、C_2,0.33μF×2、400V纸介或金属化纸介;电感L,用30W镇流器代用;二极管,2CP16或2CP31F,稳压管,2CW104。
TV has been quite popular in rural areas, some remote rural areas, the voltage is often unstable, low, and in some areas the night voltage is only about 160V. In this way, the television image is twisted or even unreadable. To solve this problem, we recommend a practical 35W AC regulator, as shown in the figure: Component Selection: R_1, 20kΩ, 2W Wirewound Resistors; R_2, 150kΩ, 1 / 2W Metal Film Resistors; C_1, C_2, 0.33 μF × 2,400V paper or metallized paper; Inductance L, 30W ballast alternative; diode, 2CP16 or 2CP31F, regulator, 2CW104.
