Abstract
An apparatus, such as a switch module, is provided. The apparatus can include an electromechanical switch structure configured to move between an open configuration and a fully-closed configuration (associated with a minimum characteristic resistance) over a characteristic time. A commutation circuit can be connected in parallel with the electromechanical switch structure, and can include a balanced diode bridge configured to suppress arc formation between contacts of the electromechanical switch structure and a pulse circuit including a pulse capacitor configured to form a pulse signal (in connection with a switching event of the electromechanical switch structure) for causing flow of a pulse current through the balanced diode bridge. The electromechanical switch structure and the balanced diode bridge can be disposed such that a total inductance associated with the commutation circuit is less than or equal to a product of the characteristic time and the minimum characteristic resistance.
