摘　　要：文章提出一个新型高升压转换器。此电路架构主要是利用耦合电感、电压箝制电路及倍压电路来达到高升压比目的。此外,储存于耦合电感中的漏电感能量能够借由开关截止期间将其能量回收至箝制电路中,因此效率得以提升,且开关上电压也能够有效地被箝制。本文中详细地对此高升压转换器作稳态动作原理分析与电路特性的探讨。最后,实际设计制作一输入为直流12V,输出为200 V/150 W高升压转换器,以其模拟与实测结果验证本电路的特性与可能性。In this paper, a new high step-up converter is proposed. The high step-up ratio is achieved by adjusting the turn ratio of the coupled inductor, voltage clamp circuit and voltage doubler circuit. Moreover, the energy stored in the coupled inductor can be recycled during the off period so that the conversion efficiency is enhanced and the power switch is effectively clamped. The steady-state operation principle of the proposed high step-up converter is analyzed in this paper. Finally, a prototype of the proposed high step-up converter, with DC input 12 V and DC output 200V/150 W, is implemented and simulated to demonstrate performance and feasibility.
