Hardware-in-the-loop evaluation of DSP-controlled converters

Translation of power electronic circuit designs from simulations into actual hardware can give rise to difficulties, regarding the implementation of control functions with embedded controllers. This task is even more difficult when the power converter must operate connected to the grid. A design framework is described in this paper, which is suitable for testing and debugging software implementations of control algorithms for such applications, under nearly ¿real¿ conditions, while avoiding risks of damage to actual hardware. An example of application is given, along with experimental results.
