Keywords: DC-DC power converters, negative output, wide conversion ratio
In this work, a new negative output (N/O) buck-boost converter, which can be applied for applications that
need wide range of inverse voltage, is proposed. It is the modification of traditional buck-boost converter and provides
inverse output voltage with wide conversion ratio. The steady state, small signal model and power losses of the
proposed converter operating in continuous conduction mode (CCM) are analyze. 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. The configuration of
the proposed new buck-boost converter circuit is simulates in MATLAB/ SIMULINK.
