Abstract

The paper presents two new the software functions of the system of software functions MAOPCs. The first software function is designed to determination the instantaneous power in the branch of linear periodically-time-variable circuit and the second software function is designed to determination of transfer coefficient of average power from input of circuit to it's output. Architecture of the system MAOPCs based on the principles of programming environment Matlab, which implies the existence of software functions and user-defined functions (functions defined by the user), and it is an open system that allows you to complement it with new functions.

The paper presents a computer experiment in which for single-circuit parametric amplifier by the Tellegen's theorem checked adequacy of calculations in the MAOPCs environment instantaneous power branches of the circuit and defined transfer coefficient of average power from its input to output.

The system of software functions MAOPCs, which is based on the frequency symbolic method is an effective tool for determination of parametric transfer functions and calculation of energy characteristics of linear periodically-time-variable circuits, in particular, parametric amplifiers. Introduction to the system MAOPCs such software functions as «PowerInTheBranch()» and «TransferCoefficientOfPower()» allowed it to calculate the energy characteristics of linear periodically-time-variable circuits, leading to increase of adequacy of modeling and improving the quality of designed equipment.
