可控硅开关电源是一种设计独特的低频开关电源。该电源采用可控硅相控半波整流,开关频率与市电同频(50Hz),开关器件(可控硅)与负载串联连接,具有效率高,稳压范围宽,与负载牵连小等优点。采用可控硅开关电源的彩电主要有香港陆氏机芯,国内部分厂家80年代初引进该机芯组装生产。现在市场上较多见的有佳丽、南宝、快乐、天虹、百花、华艺、海虹彩电等十几种牌号的彩色电视机。
SCR power supply is a unique design of low-frequency switching power supply. The power supply using SCR phase control half-wave rectifier, the switching frequency and the mains frequency (50Hz), switching devices (SCR) and the load connected in series, with high efficiency, wide voltage range, and load implicated small advantage . The use of SCR power supply color TV main Hong Kong Lu movement, some domestic manufacturers to introduce the movement in the early 80s assembly production. Now more common on the market Belle, Nanbao, happy, Rainbow, flowers, Huayi, Haihong TV, such as more than 10 brands of color television sets.
