Abstract:
A regulator for a sine wave generator unit, the sine wave generator unit comprising a load feeding power bridge connected to an output of a sine wave generator, said regulator being inserted between a feedback output of the power bridge and a reference voltage input of the sine wave generator, said regulator comprising regulation means providing a power regulation signal to the reference voltage input of the sine wave generator from a comparison between a signal at the feedback output of the power bridge and a predetermined set point signal, wherein said regulation means comprise a proportional integrating differentiating regulator comprising start-up and shut-off envelope controlling means for obtaining a controlled start-up and shut-off slopes of the signal at the load feeding output of the power bridge in addition to a control of a signal envelope between a start-up slope and the following shut-off slope.
