摘要：

In this paper, a new negative output (N/O) buck-boost converter, which can be applied for applications that need wide range of inverse voltage, is proposed. The steady-state, small-signal model and power losses of the proposed converter operating in a continuous conduction mode are analyzed. Comparisons among the traditional buck-boost converter, N/O hybrid buck-boost converter and N/O self-lift Luo converter are presented, and it is found that the proposed converter possesses a widest voltage conversion ratio in these four converters. Finally, a prototype is built, and the simulated waveforms from the PSIM software and the experimental results are presented for validation.
