Abstract

RESEARCH ON PT SYMMETRY AND SYSTEM ENERGY IN INDUCTIVELY COUPLED CIRCUITS

Zhang Miaomiao*

ABSTRACT

The parity-time (PT) symmetric system based on inductively coupledcircuits is widely used in energy transfer and passive sensing. Whenconsidering the impedance of the coupled inductor coils, the stabilityanalysis of the PT symmetric property of the coupled circuit cannot beanalytically derived from the theory of PT symmetric stability based onideal inductors. Therefore, a method for analyzing the stability of PTsymmetry based on the energy characteristics of the system isproposed. This method can effectively analyze the PT symmetricstability of ideal coupled inductors and determine the influence of the impedance of coupledinductors on the PT symmetric stability of the coupled circuit,as well as determine theconditions for re-establishing stable PT symmetry after the PT symmetric instability of thecircuit system. The research results have practical guidance significance for theimplementation of energy transfer systems.
