摘要： A driver for an electric load includes a power device having a control terminal and an output terminal for an output current, and a control module. The control module is configured to drive the power device in an auto-recovery mode by switching between activation and deactivation in the occurrence of an overcurrent condition, wherein the output current reaches a threshold current. The control module is also configured to evaluate a first time interval between a time wherein the overcurrent condition occurs, and a first time, and generate a limit signal when the time interval is equal to a time threshold. The power device is driven in a switching-off condition at least as a function of the limit signal.

摘要： A protective redundancy circuit is provided for a power tool having an electric motor. The protective redundant subsystem is comprised of: a motor switch coupled in series with the motor; a motor control module that controls the switching operation of the motor switch; and a protective control module that monitors switching operation of the motor switch and disables the power tool when the switching operation of the motor switch fails. In the context of an AC powered tool, the switching operation of the motor switch is correlated to and synchronized to the waveform of the AC input signal. During each cycle or half cycle, the motor control module introduces a delay period before closing the motor switch and the protective control module determines the operational status of the motor switch by measuring the voltage across the motor switch during the delay period.

The solid-state relay includes an output terminal for connection to a load. A sensing element is associated with the solid-state relay to sense an operating parameter associated with the solid-state relay. A feedback element controls the switch element to switch an operating state in response to the operating parameter exceeding a reference parameter. The solid-state relay changes state in response to the switch element to control an output current of the solid-state relay between an energized or de-energized state.
