摘要：

A family of transformer-less single-switch high gain Boost converters with lower voltage stress and current stress was proposed. The voltage gain of the proposed converters is G=(1+D)/(1-D). Compared to the traditional quadratic Boost converter, quasi-Z-source Boost converter and switched inductor Boost converter, the proposed converters have some advantages, including less components, lower voltage stress and current tress of active switch and part of passive components, thereby reducing the system total loss and cost and improving the conversion efficiency. The operating principle and steady-state characteristics under the inductor current continuous conduction mode (CCM) and bidirectional conduction mode (BCM) has been discussed in detail. Finally, an experimental prototype was implemented to verify the effectiveness of the proposed converters. © 2020 Chin. Soc. for Elec. Eng.
