Description

Today's automotive power consumtion is 3KW, which will increase to 10KW in next 5 years and 12V batttary is unable to provide that much power. 48-12V bi-directional convertor provides high power requirement solution with two phases each capable of running 28A.  This solution allows bidirectional current control of both phases using a C2000 control stick and firmware OCP & OVP. The 48-12V bi-directional converter removes the voltage conditioner need and distributes loads more evenly. The 48V battary is used to power high torque motors and other high power components such as A/C compressors and EPS, while no change to 12V battery loads.

Features
  • Nominal 48V- 12V bidirectional power supply
  • Dual Phase, each capable of running 28A load 
  • Can drive a total of 56A load
  • 2 SM72295 for each phase
  • One C2000 control stick card
  • GUI monitoring and control power transfer; firmware OCP & OVP
