Abstract: For DC-DC converter working in the switch operating frequency,the system is prone to produce high frequency harmonics,bifurcation and chaos,reducing the stability of system.Under proper frequency and amplitude,the change of system parameters by the parametric resonance interference method can avoid chaos system bifurcation and suppress high frequency harmonics.Our study of the voltage control mode in parallel BUCK converter shows that the parameter resonance interference method can inhibit the bifurcation and chaos with improved system stability.

Key words: chaos;bifurcation;nonlinear
