电源系统是电台的能量源泉,好的电源系统是无线电通信的基础和保障。小型无线电台通常都需要使用低压直流电,从相对电压较高的交流市电转换成低压直流电就是稳压电源的工作。稳压电源的电路形式过去主要是变压器+稳压电路的线性稳压
Power system is the energy source of the radio, a good power system is the basis and guarantee of radio communication. Small radio stations usually need to use low-voltage DC, from the relatively high voltage AC mains into low-voltage DC power supply is the work of the regulator. Regulated power supply circuit in the past mainly transformer + regulator circuit linear regulator
