MCU enhances DC-to-DC converter output for hybrid/electric vehicle applications

Last Updated: June 19, 2014

SUNNYVALE, Calif., June 19, 2014 -- Concerns about climate change and gas prices have strengthened the market for eco-friendly vehicles such as hybrid electric vehicles (HEVs) and all-electric vehicles (EVs). These vehicles use an electric motor powered by a high-voltage lithium-ion battery. For efficiency, the powerful direct current (DC) motor drive voltage is usually boosted to several hundred volts by a DC-to-DC inverter. Meanwhile, HEVs and EVs typically use the same electronic control units (ECUs) as gasoline-powered vehicles for functions like body control and instrument clusters. That means they are designed to run on a 12-V power supply. As a result, the DC-to-DC converter is also used to "step down" the Li-ion battery's few hundred volts of output to the standard 12-V DC.

For the full story on how microcontrollers can be used to enhance DC-to-DC converter output to enable greater efficiency in HEV and EV embedded systems design, check out this article on Core & Code magazine:
