Switching module for opening or closing connection between node of power supply circuit and connection node of load circuit, has controlled switch preventing current flow in switching module in direction opposed to operation direction

摘要

The module (42) has a controlled switch (47) associated with another controlled switch (48) for connecting a node (44) of a power supply circuit (40) with a connection node (A) of a load circuit (41). The former switch allows or blocks flow of current in a direction of operation according to a control signal applied to the former switch. The latter switch prevents electrical current flow in the switching module in a direction opposed to the operation direction, where the latter switch is controlled by another control signal as a function of an electric potential of the connection node.
