HRA 1~12w series 12V wide voltage 9~18v to ± 250VDC boost converter

5v/12v/15v/24v The concept of voltage amplification
The function of the amplifying circuit is to convert the energy of the power supply into a variable output , The change of these output quantities is proportional to the change of input quantities . therefore , Amplification is essentially an energy control function . Devices with energy control function are called active devices , Such as transistors 、 FET and integrated operational amplifier introduced later .
2.2.2 Performance index of amplifier circuit
Performance indicators can be divided into 3 Types . The first is corresponding to a certain amplitude , Performance of signal input with fixed frequency , This is the basic performance of the amplification circuit , Its indicators are as follows
Magnification . Magnification is an index to measure the amplification ability of an amplification circuit . It is defined as the ratio of the amplitude of the output change to the amplitude of the input change , Sometimes called gain
Input resistance .
