A Novel Dual-output DC-DC Converter Topology Without Transformer

This paper presents a dual output DC/DC converter topology without transformer, the circuit using a switch can simultaneously achieve two kinds of output, one of the outputs for the new circuit is Boost-type, the other for the Cuk-type, and can also work under the unbalanced load. In order to control the output, only one controller is used for the Boost-type output, or for the Cuk output. The operation is confirmed with successful simulation. The topological structure can be used for a number of consumer electronics products such as set-top boxes, DVD recorders, computer power supply and so on, has a practical value.
