Patent ID: 7280339

Claim:
Operating device ( 41 ) for inductive electrical actuators, comprising a power circuit ( 42 ) provided with an operating circuit ( 11 ) for each electrical actuator ( 12 ); the said operating circuit ( 11 ) comprising switch means ( 27 , 28 , 29 ) controlled selectively to regulate the current flowing through the said electrical actuator ( 12 ); the said operating device ( 41 ) additionally comprising a control circuit ( 43 ) for operating the power circuit ( 42 ), and being characterized in that it comprises: a set of control modules ( 44 ), each of which selectively operates the said switch means ( 27 , 28 , 29 ) of a corresponding operating circuit ( 11 ), and supplies at its output a state signal (S FLAG ) indicating the operating state of the said control module ( 44 ); and synchronization means ( 45 ) for receiving and processing the state signals (S FLAG ), to generate a common synchronization signal (S SINC ) for synchronizing the said control modules ( 44 ) with each other; each said control module ( 44 ) being capable of synchronizing and coordinating, in accordance with the said synchronization signal S SINC , the operating actions sent to the corresponding switch means ( 27 , 28 , 29 ) with the operating actions sent by the other control modules ( 44 ) to the corresponding switch means ( 27 , 28 , 29 ).
