Abstract:
Electric vehicle (EV) adoption is an essential step in lessening carbon emissions from the transportation
Electric cars (EVs) with a fuel cell (FC)-battery hybrid
industry. The three-phase traction motor, a three-phase two-
powertrain are an option to emerging battery EVs. In order to

prevalent EV powertrain. Due to their high energy and
FC, the low-voltage dc output of the FC is usually linked to the
power density, lithium-ion batteries typically serve as the dc
high-voltage EV battery using a dc-dc converter. In a dual-
