Switch structure and associated circuit

摘要

An apparatus, such as a switch module (100), is provided. The apparatus can include an electromechanical switch structure (102) 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 (120) can be connected in parallel with the electromechanical switch structure, and can include a balanced diode bridge (122) configured to suppress arc formation between contacts of the electromechanical switch structure and a pulse circuit (142) including a pulse capacitor (146) 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.
