چکیده
|
Nowadays, applying high step-up converters in electric cars has become very common. because the battery voltage level and fuel cells are low and requires step-up converters to lift the dc voltage level to the appropriate level for the inverter for the motor drive. conventional boost converters have countless problems such as high voltage stress on the switch, high duty factor, reverse recovery problem in diode, and switching losses. one of the practical techniques for increasing power and reducing the input ripple is the use of interleaved converters. since the interleaved structure, in addition to increasing the converter power and reducing the switches current level, also reduces the input current ripple due to the increase in the frequency of the current ripple, provided that the input inductors are not coupled because the input coupling the input inductors will extremely increase the ripple. in this paper, 3 interleaved step-up converter with soft switching are introduced.
