  • INTERRUPTING CIRCUIT FOR A RADIO FREQUENCY GENERATOR
    Publication number: 20210219391
    Abstract: An interrupting circuit (44) is configured to monitor for and detect a fault in a device (10) for generating a field of electromagnetic radiation (e-field) (34) from a radio frequency (RF) generator (24) configured to convert low voltage direct current (DC) into the e-field (34) for application to an article in the e-field (34). If a fault is detected, the interrupting circuit (44) interrupts low voltage DC between an energy reserve (46, 48) and the RF generator (24) within a predetermined time less than the time to dissipate energy stored in the energy reserve (46, 48).
