摘要：

This paper presents a new non-isolated bidirectional hybrid switched-capacitor DC-DC converter (BHSC) which achieves a high voltage conversion ratio. The hybrid characteristic is due to the switched capacitor cell that is inserted into a conventional buck/boost bidirectional converter, which also helps achieve the high conversion ratio. Apart from the high conversion ratio, the switched cell also helps reduce all passive components and the stress on the active switches, all without interrupting the input to output ground path. The stability of the converter is also addressed by using the state space averaging method (SSA), prior to the actual construction of the converter, in order to design the passive components so that possible instabilities that might occur are eliminated. The simulation results are used to confirm the initial theoretical considerations.
