DC/DC 電源轉換器在汽車的應用

This episode is to introduce you to dc/dc converter applications.

dc/dc converter has been used in many applications.

Like Industrial, Railway, and Automotive.

This time, we focus on Electric Vehicle application.

It uses dc/dc converter in different parts in the electric vehicle, like Battery Management System, ECU, Motor and Thermal system.

Next, we will show you the case study.

This case study is PTC heater.

The heater rods is powered directly from high-voltage battery.

The driver control PTC heater via CAN or LIN bus.

This two figures are block diagram of PTC heater.

The left figure is the MCU share the same ground with high-voltage battery.

In this case, it will need an isolated transceiver, and also isolated DC/DC converter to power SiC and MCU.

The right figure is MCU share the same ground with low-voltage battery. In this case, it may not need isolated transceiver. But still need isolated converter to power SiC.

Using dc/dc converters will bring benefits to the system.

Like minimize layout space, optimize thermal and EMS performance.
