Abstract :
Nonlinear phenomena are very prevalent in power electronic circuits. In this paper, rich nonlinear phenomena were studied in depth in power electronic circuit such as DC-DC converters, AC-DC converters, and DC-AC converters. It regarded voltage mode Buck converter, peak current mode Boost PFC, H bridge inverter as the object of study, elaborated the operation principle, listed in the corresponding differential equations, applied the concept of digit logic, combined the binary logic variables, set up model system and simulated these model. At last, it analyzed the complex dynamics of nonlinear circuit and provided a reliable instructor for the design of power electronic circuit.
