Why a prototype?
> Before building such equipment, we
need to answer some questions:
⢠What kind of controller (FPGA, DSP) ?
â Control algorithm, switching freq?
⢠What about the interface between simulator
and amplifier?
â Latency is the work of the devil!!
> To answer those questions, we need a
flexible reduced scale power amplifier!!

The features of the prototype
> Single phase / three-phase
> Ideal (pure) /real voltage waveform
synthesis
> Adjustable dynamics (to meet full scale
constraints)
> Adjustable topology
> Adjustable transient capability
The solution: a self-powered
multi-level converter
