Patent number: 11632829Abstract: A defrosting system includes an RF signal source, an electrode proximate to a cavity within which a load to be defrosted is positioned, and a transmission path between the RF signal source and the electrode. The system also includes power detection circuitry coupled to the transmission path and configured repeatedly to take forward and reflected RF power measurements along the transmission path. A system controller repeatedly determines, based on the forward and reflected RF power measurements, a calculated rate of change, and repeatedly compares the calculated rate of change to a threshold rate of change. When the calculated rate of change compares favorably with the threshold rate of change, the RF signal source continues to provide the RF signal to the electrode until a determination is made that the defrosting operation is completed, at which time the RF signal source ceases to provide the RF signal to the electrode.Type: GrantFiled: March 7, 2020Date of Patent: April 18, 2023Assignee: NXP USA, Inc.Inventors: James Eric Scott, Jérémie Simon, Xiaofei Qiu, Lionel Mongin, Pierre Marie Jean Piel

Patent number: 11570857Abstract: A defrosting system includes an RF signal source, two electrodes proximate to a cavity within which a load to be defrosted is positioned, a transmission path between the RF signal source and the electrodes, and an impedance matching network electrically coupled along the transmission path between the output of the RF signal source and the electrodes. The system also includes power detection circuitry coupled to the transmission path and configured to detect reflected signal power along the transmission path. A system controller is configured to modify, based on the reflected signal power, values of variable capacitors of the impedance matching network to reduce the reflected signal power. The impedance matching network may be a single-ended network or a double-ended network.Type: GrantFiled: March 21, 2019Date of Patent: January 31, 2023Assignee: NXP USA, Inc.Inventors: Jamison Michael McCarville, Pierre Marie Jean Piel, James Eric Scott, Lionel Mongin, Jeremie Simon

Patent number: 11252980Abstract: A thermal increase system includes a cavity, a first electrode disposed in the cavity, a second electrode disposed in the cavity, and a self-oscillator circuit that produces a radio frequency signal that is converted into electromagnetic energy that is radiated into the cavity by the first and second electrodes. The self-oscillating circuit includes the first electrode and the second electrode. In an embodiment, the first electrode is a first plate in a capacitor structure and the second electrode is a second plate in the capacitor structure. The cavity and a load contained within the cavity operates as a capacitor dielectric of the capacitor structure. A resonant frequency of the self-oscillator circuit is at least partially determined by a capacitance value of the capacitor structure.Type: GrantFiled: September 13, 2019Date of Patent: February 22, 2022Assignee: NXP USA, Inc.Inventors: Pierre Marie Jean Piel, Lionel Mongin, Jérémie Simon

A system controller is configured to modify, based on the reflected signal power, an inductance value of the impedance matching network to reduce a ratio of the reflected signal power to the forward signal power. The impedance matching network includes a plurality of fixed-value, lumped inductors positioned within a fixed inductor area.Type: GrantFiled: March 10, 2017Date of Patent: June 15, 2021Assignee: NXP USA, Inc.Inventors: Xiaofei Qiu, James Eric Scott, Lionel Mongin, Jérémie Simon, Pierre Marie Jean Piel
