Abstract

Abstract:

Firstly,the energy conservation theory is used to idealize the isolated half bridge circuit.Then the AC small signal mathematical model of the isolated half bridge circuit is established according to the average model method of switching network,and the open-loop transfer function of the system is obtained.On the basis,the amplitude frequency and phase frequency characteristics of the mathematical model are analyzed,and the corresponding closed-loop parameter compensation and system correction are carried out.The simulation and experimental results further verify the validity of the theoretical modeling and the rationality of the compensation parameters.

Key words: isolated half bridge circuit, switching network averaging model method, small signal mathematical model, parameter compensation
