Abstract
An interrupting circuit is configured to monitor for and detect a fault in a device for generating a field of electromagnetic radiation (e-field) from a radio frequency (RF) generator configured to convert low voltage direct current (DC) into the e-field for application to an article in the e-field. If a fault is detected, the interrupting circuit interrupts low voltage DC between an energy reserve and the RF generator within a predetermined time less than the time to dissipate energy stored in the energy reserve.
