Abstract
A power circuit provided with an operating circuit for each electrical actuator and including a set of switches controlled selectively to regulate the current flowing through the electrical actuator. The operating device includes a control circuit which can cause the operation of the power circuit and in turn includes a set of control modules, each of which can selectively operate the switches of a corresponding operating circuit, and can supply a state signal (SFLAG) indicating the operating state of the control module. A synchronization module receives and processes the state signals (SFLAG), to generate a common synchronization signal (SSINC) which synchronizes the control modules. Each control module being capable of coordinating the operating actions sent to the switches of the corresponding operating circuit with the operating actions sent by the other control modules to the corresponding switches, in accordance with the synchronization signal (SSINC).
