High- government agency dc/dc converters argon a authoritative component of todays emerging vehicular technologies much(prenominal) as hybrid-electric, battery-electric, and fuel-cell vehicles. Typically, a voltage rising slope is required to maltreat up the low voltage of the fuel cell or battery to the gamey voltage required by the grip motor inverter. For these it is necessary that the size and mass of the converter should be small to facilitate packaging. This is due to the higher power parsimoniousness and to provide higher fuel economy due to cut down vehicular mass. Furthermore, the converter should feature a simple aim with high-efficiency operation over the entire load range. The large peaceful components used in high-power dc/dc boost converters, specifically the large boost inductor, comprise a major(ip) part of the mass of the converter. Higher frequency operation helps in reducing the size of the passive components. But there are 2 major obstacles to achieving high-frequency operation of the high power dc/dc converters. First, the switching losses increase proportionally with the increase frequency, which reduces the converter efficiency and increases the chill requirements. A large cooling system adds to the overall cost and mass of the converter system.
Second, the high power insulated gate bipolar transistors (IGBTs) used in these converters are limited to hard-switching operation at about 30 kilohertz or less , depending on the power level.
In pose to overcome all these drawbacks possessed by the conventional dc/dc boost converters, these are replaced by the capacitor switched regenerative snubber circuited dc/dc boost converters
A.BASIC CONCEPTS OF CONVERTERS
Converter is an electronic circuit which converts a source of alternating or direct current (AC or DC) from one voltage level to another. It is a class of power converter. DC/DC converters can be classified into two types. They are: a) boost converters b) buck converters.
A boost converter (step-up converter) is a DC-DC...If you want to get a full essay, align it on our website: Orderessay
