Summary: The methods of apparent power decomposition in one-port networks with periodically operated switches are analyzed.Power phenomena that give rise to the existence of apparent power components other than the active power are recognized.It is shown that regarding source power factor compensation the frequency- -domain based methods of apparent power decomposition are more effective than the time-domain based methods. The same conclusion does not apply to the multiport (polyphase) networks.The main reasons are due to the ambiguous meaning of the concept of polyphase apparent power and due to the requirement that in order to improve the power properties of polyphase source networks it is necessary to find out methods of non-active power components compensation on the instantaneous basis. From the power applications point of view, the most important examples of the networks with periodically operated switches are electronic power converters.Starting from the principle of power balance at each frequency, conversion process in electronic power converters as well as conversion properties of network devices are explained.

Keywords: periodically operated switches , apparent power components , power conversion at frequency , electronic power converter

Research goals: The development of a more complete power theory of networks with periodically operated switches for the purpose of: a) the choice of power circuits of electronic power converters more compatible with the source network characteristics ; b) the choice of non-active power components compensation methods in one-port nonlinear networks and in multiport nonlinear networks ; c) the development of the methods and equipments for measurement of the particular components of apparent power in nonlinear networks .
