A novel isolated buck-boost converter
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009This paper proposed a novel Isolated Buck-Boost PWM DC-DC converter circuit. The topology which merged buck-boost mode with flyback mode can share the transformer and switch. Not only isolated buck-boost mode current but also flyback mode current added on the one output current of the converter because the topology merged buck-boost mode with flyback ...

High gain buck-boost matrix converter
2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016Boosting factor of power converter is a critical requirement for high voltage low power applications. There are many extended DC-DC converter topologies available for boosting output voltage beyond the traditional boost converters. However, for direct AC-AC conversion boosting factor of four can be achieved using single inductive element or impedance ...

Dual active bridge buck-boost converter
2009 IEEE Energy Conversion Congress and Exposition, 2009A novel isolated bidirectional dc/dc converter suitable for high power applications is proposed. The proposed converter has bidirectional power flow capability with low device ratings for a wide source voltage range. The converter is controlled by varying the duty cycle and phase of the firing pulses, to achieve power flows in both directions and ...

The buck-boost DC/DC converter
INTELEC - Twentieth International Telecommunications Energy Conference (Cat. No.98CH36263), 2002In the last few years the requirements for reduction of costs and thereby of the number of components and protection circuits in DC/DC-converters, as part of the overall power supply systems, have increased significantly. The large number of new circuit topologies with optimized circuit parameters has been proposed and in some cases even produced.

Buck-boost DC/DC converter for aeronautical applications
2010 IEEE International Symposium on Industrial Electronics, 2010In this document a DC/DC converter for power conversion between +28V/+270V voltage levels is presented, and the main characteristics of the converter are discussed. The topological structure is first introduced, outlining the hardware components used and the modular approach. The step-down (or Buck) and step-up (or Boost) modulations are then discussed,
