Abstract
In this paper, the small-signal modeling of boost converter with LCL ripple cancellation network(RCN) has been derived and analyzed. In order to analyze the dynamic and static characteristics of boost converters after adding the RCN, a conventional synchronous boost converter (CSBC) and a boost converters with LCL RCN under 36-V input voltage, 50-V output voltage and 500-W output power have been designed and built. The experiment results show that the RCN can achieve input current ripple cancellation of boost converter in all power range. Meanwhile, both converters have the similar open-loop frequency responses and dynamic characteristics under the same PI control with the load transient recovery time less 3ms, which proves that the proper RCN parameter will not bring significantly changes on the dynamic and static characteristics of the CSBC.
