Currently I am working with research on space vector pulse width modulation. I have simulated svpwm for three phase bridge inverter. How can I implement its hardware practically?
You can implement your inverter by assembling the power switching circuit from either PMOST or IGBT with the proper ratings. Then you generate their control signals to produce certain output waveform by a micocontroller board. The micro controller is interfaced with the power switches by an appropriate driver circuit. It receives also its control inputs by sensing the currents and voltages from the load. Then you need to develop your software to operate the system.
You can find much more details on the practical implementation in the links:
Since you have simulated svpwm for three phase bridge inverter therefore it will be better and easier if you interface the generated control signals to the hardware.
For a microprocessor implementation please look for one with three hardware counters in it. Thus after calculation of the durations for the vectors you only have to load them to the counters and then control the transistors by interrupts produced by the counters. In the SAMISTAR frequency converters in the 80's an Intel 80186 operated this way.
