svc稳压电源价格50-300不等。.功耗小，效率高。在图1中的开关稳压电源电路中，晶体管V在激励信号的激励下，它交替地工作在导通―截止和截止―导通的开关状态，转换速度很快，频率一般为50kHz左右，在一些技术先进的国家，可以做到几百或者近1000kHz。这使得开关晶体管V的功耗很小，电源的效率可以大幅度地提高，其效率可达到80%。.体积小，重量轻。从开关稳压电源的原理框图可以清楚地看到这里没有采用笨重的工频变压器。由于调整管V上的耗散功率大幅度降低后，又省去了较大的散热片。由于这两方面原因，所以开关稳压电源的体积小，重量轻。.稳压范围宽。从开关稳压电源的输出电压是由激励信号的占空比来调节的，输入信号电压的变化可以通过调频或调宽来进行补偿，这样，在工频电网电压变化较大时，它仍能够保证有较稳定的输出电压。所以开关电源的稳压范围很宽，稳压效果很好。此外，改变占空比的方法有脉宽调制型和频率调制型两种。这样，开关稳压电源不仅具有稳压范围宽的优点，而且实现稳压的方法也较多，设计人员可以根据实际应用的要求，灵活地选用各种类型的开关稳压电源。.滤波的效率大为提高，使滤波电容的容量和体积大为减少。开关稳压电源的工作频率目前基本上是工作在50kHz，是线性稳压电源的1000倍，这使整流后的滤波效率几乎也提高了1000倍。就是采用半波整流后加电容滤波，效率也提高了500b倍。在相同的纹波输出电压下，采用开关稳压电源时，滤波电容的容量只是线性稳压电源中滤波电容的1/500―1/1000。
