| Abstract |
In automotive applications piezoelectric actuators (used as injectors) typically require more than 150V in order to be driven in a smaller time with respect to magnetic actuators, allowing for example more precise injections in the same motor cycle. This is a big concern in automotive environment, where the 12V battery voltage is still the main power source available. In this paper an efficient high-step up DC/DC converter is presented for interfacing the standard 12V battery with the high voltage DCBUS used for piezoelectric actuators system. In the proposed converter, two coupled inductor boost converters are interleaved and controlled by an FPGA. Design and analysis of the proposed converter are presented. Finally experimental results are provided for verification of the proposed converter. |
