Abstract V 2 control technique with fast transient response is applied to Cuk converter, and the principle of V 2 controlled Cuk converter operating in continuous conduction mode (CCM) is analyzed. The time-average equivalent circuit modeling approach considering equivalent series resistance (ESR) of output capacitor is used to derive the transfer functions of CCM Cuk converter. Subsequently, the accurate small signal models of V 2 controlled CCM Cuk converter and peak current controlled CCM Cuk converter are established, and the control-output transfer function and output impedance are further deduced. The transient characteristics of the two converters are compared in frequency domain, and their time-domain simulation models and experimental circuits are established. Then, the steady-state and transient performance of the two converters are analyzed and compared. The results show that compared with peak current controlled CCM Cuk converter, V 2 controlled CCM Cuk converter shares the same steady-state performance, but has better performance in transient response speed.
