MULTIPLE CAVITY MICROWAVE OVEN DOOR

摘要

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.

主权项

1. 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, comprising: a generator power supply connected between a power source and the RF generator, the generator power supply having at least one energy reserve and at least one power conversion circuit to convert power to low voltage DC for the RF generator, and at least one interrupting circuit configured to monitor for and detect a fault in the device, and if a fault is detected, to interrupt the low voltage DC between the at least one energy reserve and the RF generator within a predetermined time less than the time to dissipate energy stored in the at least one energy reserve.
