This converter is applicable in hybridizing alternative energy sources in electric vehicles. In fact, by hybridization of energy sources, advantages of different sources are achievable. In this converter, the loads power can be flexibly distributed between input sources. Also, charging or discharging of energy storages by other input sources can be controlled properly. The proposed converter has several outputs with different voltage levels which makes it suitable for interfacing to multilevel inverters. Using of a multilevel inverter leads to reduction of voltage harmonics which, consequently, reduces torque ripple of electric motor in electric vehicles. Also, electric vehicles which using dc motor have at least two different dc voltage levels, one for ventilation system and cabin lightening and other for supplying electric motor. The proposed converter has just one inductor. Depending on charging and discharging states of the energy storage system (ESS), two different power operation modes are defined for the converter. In order to design the converter control system, small-signal model for each operation mode is extracted. The validity of the proposed converter and its control performance are verified by simulation and experimental results for different operation conditions

However, there are some well-known technical limitations to FCs: they have slow power transfer rate in transitory situations, and a high cost per watt. This case is the reason for which FCs are not used alone in the EVs to satisfy the load demands, particularly during startup and transient events. So, in order to solve these problems, usually FC is used with energy storage systems (ESSs) such as batteries or supercapacitor (SC). Furthermore, the association of FC and ESSs leads to a reduction of the hydrogen consumption of the FC. FC and ESSs such as battery and SC have different voltage levels. So, to provide a specific voltage level for load and control power flow between input sources, using of a dc–dc converter for each of the input sources is need. Usage of a dc–dc converter for each of the input sources leads to increase of price, mass, and losses. Consequently, in hybrid power systems, multiinput dc–dc converters have been used. Multiinput converters have two main types, isolated multiinput dc–dc converters and nonisolated multiinput dc–dc converters. In the following sections, two main types of multiinput converters are investigated In isolated multiinput dc–dc converters, high-frequency transformer is used in order to make electric isolation. Highfrequency transformer provides electric isolation and impedance matching between two sides of converter.

Usually isolated dc–dc converters, in addition to high-frequency transformer, have high-frequency inverter and rectifier. The power flow between input and output sides is controlled by adjusting the phase shift angle between primary and secondary voltages of transformer. Isolated dc–dc converters have several types such as half-bridge isolated converters, full-bridge isolated converters, boost half-bridge isolated converters, and combinational multiport isolated converters. Due to using of transformer, isolated dc–dc converters are heavy and massive. These converters require inverters in input sides of transformer for conversion of input dc voltage to ac and also need rectifiers in outputs of transformer for conversion of ac voltage to dc. Therefore, in all input and output terminals of these converters, several switches are applied which leads to increase of cost and losses. Furthermore, transformer has losses in its core and windings. Because of the aforementioned drawbacks of isolated multiinput dc–dc converters, usage of nonisolated multiinput dc–dc converters in electric vehicle applications seems more useful

The sharing strategy depends on the operation that can be in the discontinuous mode, with clamping at zero of the current, or in the continuous mode. There are three time slots: one used to charge the inductor and two used to discharge the inductor into the two loads.

The proposed converter has just one inductor. The proposed converter can be used for transferring energy between different energy resources such as FC, PV, and ESSs like battery and SC. In this paper, FC and battery are considered as power source and ESS, respectively. Also, the converter can be utilized as single input multioutput converter. It is possible to have several outputs with different voltage levels. The converter has two main operation modes which in battery discharging mode both of input sources deliver power to output and in battery charging mode one of the input sources not only supplies loads but also delivers power to the other source (battery). For each modes, transfer functions matrices are obtained separately and compensators for closed loop control of the converter is designed. It is seen that under various conditions such as rapid rise of the loads power and suddenly change of the battery reference current, output voltages and battery current are regulated to desired values. Outputs with different dc voltage levels are appropriate for connection to multilevel inverters. In electric vehicles, using of multilevel inverters leads to torque ripple reduction of induction motors. Also, electric vehicles which use dc motors have at least two different dc voltage levels, one for ventilation system and cabin lightening and other for supplying electric motor. Moreover, in grid connection of renewable energy resources like PV, using of multilevel inverters is useful. Finally, operation of this converter was experimentally verified using low-power range prototype. .
