| Bidirectional DC/DC converter is based on the demands of the regulation ofenergy bidirectional DC/DC converter. In the DC uninterruptible power supplysystems, aerospace power systems, electric cars and solar converter and other occasionshave a wide range of applications. This paper presents a by two channel interleavingparallel integrated magnetic coupled inductor bidirectional DC/DC converter, theconverter two channel Buck+Boost bi-directional DC/DC converter all the passages ofthe inductor for a coupled inductor. This paper analyzes in detail the interleavedmagnetic integrated bidirectional DC/DC converter in Buck and Boost modes understeady state ripple current and transient response speed, and puts forward two channelinterleaving parallel magnetic integrated bidirectional DC/DC converter operating inBuck mode and running in Boost mode design criteria, namely in the design of theconverter, should be based on the duty ratio of the size and the steady state phase ripplecurrent and transient total output current in response to the speed of the technicalrequirements, using the given design formulas and design area integrated magneticcoupled inductor reverse coupling coefficient. The isolation two-way DC/DCconverter has fast response, current ripple small and so on characteristics widely appliedin medium and small power occasions, but with the production practice request, highpower equipment gradually used in daily production and life, not isolation two-wayDC/DC converter can not meet the need of production and life of people, isolationtwo-way DC/DC converter arises at the historic moment, in this paper, the isolationtwo-way full bridge DC/DC converter as a research object to carry on the analysis.Isolation two-way full bridge DC/DC converter have high frequency transformer tojoin, namely realize the electrical isolation and can realize voltage transformation.Through simulation and experiments prove the correctness of the theory analysis. |
