在电路中,从供给功率的意义上来说,电源是必不可少的而且也是非常重要的。然而,随着电路的晶体管化,尤其是集成电路的广泛应用,为了充分地发挥电路的作用并保证其工作稳定,必然对电源提出更严格的要求。对电源的要求之一是输出电压的稳定化。众所周知,电源的电压基本上是首先从适当的变压器获得交流电压,经整流后变为直流供电路使用。但是,电源的输出电压是随输入的交流电压的变化和负载电流的变化而变化的,从而引起电路性能的变化。为了减少电源输出电压的变化,必须对电源变压
In the circuit, from the power supply point of view, the power supply is essential and also very important. However, with the transistorization of the circuit, especially the wide application of the integrated circuit, in order to fully exert the function of the circuit and ensure its stable operation, it is bound to put more strict requirements on the power supply. One of the requirements of the power supply is the stabilization of the output voltage. As we all know, the power supply voltage is basically the first to obtain from the appropriate transformer AC voltage, after rectification into a DC power supply circuit. However, the output voltage of the power supply varies with the change of the input AC voltage and the load current, thereby causing the change of the circuit performance. In order to reduce the power output voltage changes, the power transformer must be
