| Abstract |
In cycloconverters, thyristor firing time is usually based upon an internal voltage control, which gives rise to some embarrassing penalties. Our paper will show how these disadvantages are strongly reduced with a direct command from a microprocessor-based current controller. A hierarchical microprocessor structure optimizes control functions, man/machine dialogue and diagnosis. Simulations and experiments on a 15 kVA prototype brought this development to a successful issue. A higher power equipment (3 MVA AC motor) is now being tested. |
