Application of network analyzer in measuring the performance functions of power supply

Abstract

Frequency response analysis is critical in understanding the steady- and transient state behaviour of any electrical network. To study the system behaviour analytical model of the system is required. If the system is well understood it may be easy to develop an analytical model, and hence frequency response can be determined. But practical systems have non-idealities (or complex) which are difficult to simulate. Hence, measuring the frequency response of any black box (electrical network) makes the job practically simpler. Network analyzer or frequency response analyzer is used to determine the frequency response of an electrical network. This paper deals with the application of network analyzer in measuring the performance functions of switched-mode power supplies, which is to validate the analytical model of power supply.
