Summary:串并联补偿型感应耦合电能传输（inductively coupled power transfer，ICFF）系统在负载变轻时会发生频率分叉现象，传统变频控制的方法难以使系统稳定。针对这一问题，将自持振荡控制（self—sustain oscillation control，SSOC）理论应用到IC胛系统中。首先，分析变频控制下发生频率分叉时ICPT系统不稳定的原因。其次，用描述函数法建立ICPT系统的自持振荡控制系统，并通过Nyquist稳定性判据分析了系统的稳定性。最后，在实验样机上实现了ICPT系统的自持振荡控制。当负载变轻而发生频率分叉现象时，自持振荡器可以使系统自由振荡而趋于稳定，其动态性能良好，并且始终保持开关管的零电压开通（zero voltage switch，ZVS）状态。

Bifurcation occurs in the Series-Parallel compensation type IPCT （ inductively coupled power transfer, ICPT） system, when load become light. By using traditional VF （ vary frequency） control meth-od, this system is unstable. Aiming at this problem, the SSOC （Self-sustain oscillation control, SSOC） theory was applied to the ICPT system. First, the reason of ICPT system under VF control with bifurcation was explained. Then, ICPT system based on SSOC is derived by describe function method and the stabili-ty of the self-sustained oscillation was investigated using Nyquist stable criterion. Then, an ICPT system based on SSOC prototype was constructed. Finally, experimental results show that, when bifurcation oc-curred, this system can become stable under the control of SSOC. It has a good dynamic p
