The DC-DC converter is a key component in hybrid and EV architectures, converting the higher voltage bus (MH – 48 V or EV/HEV – 100s of V) to the traditional 12 V power bus, from where most electrical loads are powered.
There is extreme downward cost pressure on design and test, across the DC-DC converter development life cycle. With silicon (Si) based power converter designs, most DC-DC converters are water cooled. The additional cooling design cost for the HEV/EV manufacturer is passed on to the design and test engineers, requiring reservoirs, pumps, and hoses to cool the DC-DC converter during design and test. So, manufacturers are minimizing the number of liquid-cooled modules by integrating multiple power converter applications into a single module (e.g. DC-DC converter+ Onboard Charger). In addition, designers are starting to adopt new power semiconductor technology by using Wide Bandgap (WBG) devices.
