Thank you and have a nice day. The emergence of various types of converters greatly expands the scope of use of various instruments (devices), making the automatic control system more flexible and adaptable sex. The basic function of various converters is to convert information into a form that is convenient for transmission and processing. It is required that the information is not distorted, distorted, delayed, etc. during the conversion process. Therefore, the linearity, input and output impedance matching and isolation of the converter have certain Requirements: ? Linear characteristics. It is required to have a good proportional relationship between the output signal Y of the converter and the input signal X, that is, Y=KX+A, where K and A are constants. ? input impedance and output impedance. The converter input impedance and output impedance must match the input and output meters to obtain high conversion accuracy. ? isolation characteristics. Input circuit, output circuit and power supply circuit should be isolated from each other in DC potential, and the grounding points of input and output circuit F should be separated to improve anti-interference ability.
