A Nonisolated Multiinput Multioutput DC-
DC Boost Converter for Electric Vehicle
Applications
Abstract
Introduction:
FCs generate electric energy, rather than storing it, and
continue to deliver the energy, as long as the fuel supply is
maintained. 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.
Existing system:
A DC-DC switching regulator with multiple outputs time-
shares the inductor current among different loads. 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.
Proposed system:
In this paper, a new multiinput multioutput nonisolated
converter based on combination of a multiinput and a
multioutput converter is proposed. The proposed converter
compared to similar cases has less number of elements. This
converter can control power flow between sources with each
other and load.
