In this paper, a new hardware/software design and
implementation of an Induction Machine (IM) drive control
topology is presented. Power electronic applications such as threephase
inverter require highly accurate switching frequency. This
design uses a System on Chip (SoC) approach and implemented
on a Field Programmable Gate Array (FPGA). The on-chip
processor is used for high level programing while the FPGA’s
programmable fabric is used to create precise gating signals for a
three-phase inverter. These signals are generated in the hardware
side of the design. Floating-point calculations and control flow of
the whole design are managed by SoC. This method is suitable
for any power electronic application where precise gating signals
are required. The methodology used in this solution is explained
and experimental results are presented.
