Combined Solid-state AC/DC switch for laboratory applications

Inhalt:
Appropriately designed solid-state AC and DC switches allow for the precise modification of load or feeding conditions in laboratory applications. In this way the reaction of a system or device under test to quickly changing conditions can be measured. This paper presents the concept and realization of such a solid-state AC/DC switch, which offers easy control by fiber-optic triggering. The switch is able to switch on and off AC as well as DC currents and voltages even in inductive circuits. Measurement results verify the functionality of the system.
