As a part of the EECS 418 Power Electronics course at the University of Michigan, during the Fall 2019 semester, our final project has been to realize a DC/DC converter to efficiently drive an automotive headlight. The circuit was designed and built from our own designs and discrete components. The final circuit consists of 2 DC/DC converters, A boost converter and a sequential buck converter. Each converter is driven by a linear ramp generator into a controller. The boost converter utilizes a feedforward controller and the buck converter uses a feedback converter. The final project is able to drive and LED over a controllable current range of 0.4 to 1.3 Amps, over an input voltage range of 6-12V with an efficiency as high as 96%. The initial board prototype was designed to be easy to debug, troubleshoot and understand as well as compact and efficient. Numerous jumpers and test points were included to aide in testing.
