摘要： A solid state radio frequency generation system is provided for an electromagnetic cooking device having an enclosed cavity. The radio frequency generation system includes: an RF feed for introducing electromagnetic radiation into the cavity to heat a food load; a high-power RF amplifier coupled to the RF feed, the amplifier comprising at least one amplifying stage configured to output a signal that is amplified in power with respect to an input RF signal; a small signal generator for supplying the input RF signal to the amplifier; and a switching power supply unit including a single DC-DC converter that converts AC mains power to low voltage DC for supply to the amplifier, and a controller configured to adapt an input current from the AC mains power to form a predefined periodic waveform with the same frequency as the AC mains power for supply to the small signal generator.

摘要： An electromagnetic energy delivery system includes a set of radio frequency channels; each channel configured to receive a set of reference signals. Each channel further includes a compensation component and a phase-locked loop component. The compensation component can be configured to determine a phase difference between at least a subset of the reference signals; compare the phase difference with a predetermined reference phase difference; and determine a reference signal compensation offset value based on the comparison of the phase difference and the predetermined reference phase difference. The phase-locked loop component can be configured to generate a phase-shifted signal wherein the phase shift is based on at least the reference signal compensation offset value.

摘要： An electromagnetic energy delivery system includes a set of radio frequency channels. Each channel includes a radio frequency feed, at least one high-power amplifier and a phase-shifting component. Each high-power radio frequency amplifier includes at least one amplifying component configured to output a periodic signal that is amplified in power with respect to an input radio frequency common reference signal. The phase-shifting component is configured to modulate the phase of the output periodic signal with respect to the input radio frequency signal. A controller coupled to the set of radio frequency channels can be configured to cause the output periodic signals from each of the radio frequency channels is to have a time-varying phase difference relative to the common reference signal and a phase difference relative to the other output periodic signals that is constant when averaged over time.
