Paper Title
Bidirectional DC-DC Buck-Boost Converter For Automotive Applications
  Dabhi Ravi K,  Rital R.Gajjar,  Gunjan Tetar,  Vyas Mayank

As the development in car, electronics and automatic parts has the capacity of current 14V system no longer meets the demand of on board devices. An upgrade is imminent in order to be backward compatible with the existing system (48v) and not to introduce extensive modification; a dual 48/220V system is being developed as a compromising solution. Based on this new system, this project deals with the new bi-directional DC/DC converter. This new converter is able to conduct closed loop control depending on current direction without changing the hardware control system of the vehicle. This bi-directional DC/DC converter basically uses a combination of Buck and Boost converter; so that it can provide voltage to both types of loads, i.e. 48Volt loads and 220Volt loads as well, without affecting the existing system. Conventional converter has some disadvantages like higher switching losses complex system. To overcome this problems proposed converter is introduced to achieve advantages like low switching losses, simple control and compact in size. Switching losses are reduced by using the soft switching techniques

Keywords- Battery, Inverter, Bidirectional Buck-Boost Converter
