Comparison of Isolated and Non-Isolated Bidirectional DC-DC Converter Fed PMDC Motor
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
This paper includes designing and implementation of a bidirectional DC-DC converter which is fed from permanent magnet DC motor which can also be used as traction system for hybrid electrical vehicle system. The major problem of HEV is the battery storage system, in order to overcome this we are using bidirectional converter; this improves the overall efficiency of HEV bidirectional converter works in either direction i.e. in regenerative mode or in motoring mode. In motoring mode the converter works as the boost converter, thus the voltage will be boosted, current will be less, the copper losses are negligible and efficiency of the system is more. In regenerating mode the system act as buck converter, in this mode the battery gets charged. And thus the efficiency of the system is high. In order to reduce the switching losses the ZVRT technique is used. Hybrid vehicle includes the benefits of engine, electric motor and batteries in order to provide fuel improvement economy. The necessity of converter in this for charging and discharging of batteries so the process of combining the charging and discharging in one circuit topology is known as bidirectional dc-dc converters.
