Abstract

Two concepts are combined in this paper. First, the tristate concept, where the electronic switch of a DC/DC converter is replaced by a combination of two electronic switches and an additional diode. This leads to two interesting features: first the voltage-transformation ratio can be linearized and second the system can be transferred into a phase minimum system, which makes the control easier. The second two tristate Boost converters are combined to a floating double Boost converter. The basic function of the converter is explained. The large and the linearized small signal models are derived, transfer functions calculated, and Bode plots drawn. The dynamic behavior is studied with transfer functions and by circuit simulations done with LTSpice. The inrush is studied and a modification of the converter is shown to avoid dangerous overcurrents.
