Full Range Soft Switching Buck Boost with PI

ABSTRACT:

A new method for deriving isolated Buck-Boost (IBB) converter with single-stage power conversion is proposed in this paper, and novel IBB converters based on high-frequency bridgeless interleaved Boost rectifiers are presented. The semiconductors, conduction losses, and switching losses are reduced significantly by integrating the interleaved Boost converters into the full-bridge diode-rectifier. Various high-frequency bridgeless boost rectifiers are harvested

Based on different types of interleaved Boost converters, including conventional Boost converters and high step-up Boost converters with voltage multiplier and coupled inductor. The full-bridge IBB converter with a voltage multiplier.


EXISTING SYSTEM:

The non-isolated Buck cell in the non-isolated two-switch Buck-Boost converter with an isolated Buck cell, the structure of the IBB converters presented. Although a wide voltage gain range with flexible control can be achieved, it should be noted that the conversion efficiency will be hurt by the cascaded two-stage conversion architecture due to the additional conduction and switching losses.


PROPOSED SYSTEM:

Based on the proposed bridgeless Boost rectifiers, novel IBB converters can be derived by employing the input stage of an isolated Buck converter as the primary-side circuit of the IBB converters. The primary-side circuit can be full-bridge, half-bridge, or three-level half-bridge, etc., as shown. Since the focus of this paper is the boost rectifiers, only the IBB converter topologies with full-bridge input stage are shown. Obviously, the input stage of the IBB converter is a Buck-cell, the output stage is a bridgeless Boost cell, and the two cells are linked by a high-frequency inductor and transformer. This structure is similar to the non-isolated two-switch Buck-Boost converter with pi control.
