Microwave Enhanced Combustion with Feedback Frequency Control for Dynamic Impedance Matching: 10,781,786


A system and method for generating microwaves for microwave enhanced combustion (MEC) input to an MEC antenna of an internal combustion engine. The system uses a directional coupler to deliver the MEC input signal to the MEC antenna and to receive a reflected power signal from the MEC antenna. A feedback path determines a desired frequency, based on the reflected power and using an impedance-matching controller that matches the reflected power to a desired frequency value. Additional inputs, such as various engine conditions, can also be used to determine the desired frequency.
