Integrated Dual Output Buck Boost converter for industrial application

Now a days most of the fields such as industries, telecommunication, plug in hybrid vehicles etc, there will be different voltage level because of the auxiliary circuits in addition to main power circuit. In such system, Single Input Multiple output (SIMO) dc to dc converters have very good place and researches on SIMO dc to dc converters are worthy. Integrated Dual Output Buck Boost converter is one of the SIMO dc to dc converter which yields one step up output and one step down voltage. This converter is developed by replacing the switch in conventional boost converter by two series switches and taking a lowpass filter from the two series connected switches. This can be extended to N outputs which require on only N switches. But in conventional converters 2N switches are required. So the proposed converter reduces the bill amount. The cross regulation and voltage regulation further can be reduced by N+1 switches for N outputs. This converter does not require any other circuit components in order to achieve good cross regulation. So that it again reduces the cost which will be an attractive feature in modern market. In order to check the behavior of the converter simulation is carried out in MATLAB environment. The simulation results validate the operation of the converter.
