2.2 Boost/Sepic Architecture

In the Boost/Sepic architecture, Boost/Sepic is usually used as a front-stage voltage pre-regulator to convert the 12V voltage of the low-voltage battery into a stable input voltage. LLC, DC-DC module and other converters can be added to the rear stage. The Boost/Sepic architecture is shown in Figure 2-2.
