The TIDA-00364 TI Design provides a reference solution for 3-phase MOSFET based Inverter to drive AC Induction Motor for traction in Forklifts. The Inverter is powered from 48 Vdc lead acid battery. It is designed to deliver 5 KW of output power and can handle continuous motor currents of up to 130 Arms with suitable cooling setup. High current rating is achieved by using multiple MOSFET’s (CSD19536) in parallel, mounted on to thermal clad PCB. 120 V Half bridge MOSFET gate driver with 4 Apk source/sink current is been used to control the MOSFET’s. This design incorporates techniques and measures to operate MOSFET in parallel.

  • Operates from 48 Vdc lead acid battery system
  • Continuous output current up to 130 Arms
  • Inverter efficiency > 95%
  • Operating temperature from -20oC to 55oC
  • Uses 5 NEXFET (CSD19536KTT) in parallel with having high figure of merit
  • Half bridge gate driver (UCC27211) with 4 Apk source and sink capability
