The powerful DTI8 can be used to control different motor types. The power output stage is based on the highly efficient, resonant SoftSwing® topology, which was developed and patented by BRUSA Elektronik AG. The SoftSwing® topology achieves minimal switching losses. This allows applications with motor frequencies of up to 3 kHz. Due to its compact and lightweight design, the DTI8 is suitable for almost all applications and predestined for use in high performance drives.


  • Resonant SoftSwing® topology for minimal switching losses and superior EMC properties
  • Patented liquid pin© cooling system for optimal temperature behavior and best performance
  • Parameterizable for third-party motors
  • Control of one three – phase or one six – phase motor
  • Active interlock
  • Active short circuit
  • Redundant high-voltage power supply for limp home functions

The DTI8 inverter is in A-sample status
