This paper presents function of a non-confined bidirectional DC-DC converter with high voltage pick up. The proposed converter has a simple structure, low cost and ease of control. It consists of two boost converters to enhance the voltage pick up and efficiency to be high because the input current is divided to the inductors. The voltage pick up of the bidirectional dc-dc converter is more than the ordinary fell bidirectional buck/boost converter in the progression up mode. Furthermore, the voltage pick up of the bidirectional dc-dc converter is not as much as the traditional fell bidirectional buck/boost converter in the progression down mode. In order to charge and discharge the battery, a bidirectional converter is needed. The buck dc-dc converters are utilized as a part of the applications where the required yield voltage is lower than the source voltage. Plus, the lift dc-dc converters are utilized as a part of the applications where the required yield voltage is higher than the source voltage. The proposed converter can work in wide voltage range than the conventional cascaded bidirectional buck/boost converter and for better pick up performance of the proposed converter; it is compared with the conventional converter. The non-confined bidirectional DC-DC converter is assessed using MATLAB/Simulink (MLS) with the SimPowerSystem block set and the results of simulations are presented to evaluate the behaviour and feasibility of the proposed topology. The circuit is simulated with 25V input voltage for an output voltage of 250V in step-up mode and in step-down mode it is vice-versa. The task of proposed framework has been discovered palatable.
