Abstract:
Magí Margalef Boquera Control design of a multiphase 12V-48V DC-DC Set-up converter Final Master's Project Adviser: Dr. Àngel Cid Pastor and Eladi Homedes Pedret Master’s Degree in Industrial Engineering Summary This project presents the design of an analogic control for a Boost converter DC-DC 12-48V; which must ensure that the system is stable at all times, working in a power until 3000W. The control design is based on a current intern loop (Peak Current Control Mode), a current extern loop (Current Control Mode) and a voltage extern loop (Voltage Control Mode). The systems that work with Peak Current Mode Control, is present the RHP zero (it is located at right plane of s domain), which makes the control design very difficult, because it destabilizes the system. There is a trade-off between the stability and the speed of the Boost converter. The Boost converter is implemented to Mild Hybrid cars (48V Technology), which have to allow the optimal communication between the typical 12V battery and the innovate 48V battery. Tarragona 2016
