Control strategy for bi-directional DC/DC converter.

摘要

DC/DC converters were widely used for DC voltage conversions. There are various types of DC/DC converters, i.e., buck, boost, fly back, etc. Nowadays bidirectional DC/DC converter topology is becoming very popular. Bidirectional DC/DC converter is used widely in electric cars. Electric cars are new inventions and it is the next version of the hybrid car. The electric cars basically are fed from electricity and runs on the electricity depending upon its range. Bidirectional DC/DC converters are used here, where one converter will work as buck converter or boost converter depending upon the direction of power flow.;This paper mainly focuses on control strategy for bidirectional DC/DC converter along with its design and its simulation results. Control strategy is used to control the direction of the converter based on the battery voltage as well as DC bus voltage.
