OPTIMISATION OF RESONATOR EXCITATION FREQUENCY Russian patent published in 2010 - IPC H05H1/24 F02P3/45 F02P5/145 

FIELD: electrical engineering.

SUBSTANCE: invention relates to resonator supply with voltage over 200 V with frequency over 1 MHz and, particularly, to resonators incorporated with ignition systems. ICE RF-ignition system control device (2) comprises interface (21) to receiver ICE parametre measurement signals, interface (24) of command signal output, memory module (26) (MM), command signal frequency module (25) and command signal output module (27). Module (25) generates command signal depending upon measurement signals generated at reception interface and ratios saved in MM (26). Module (27) outputs certain-frequency command signal to output interface. Control device can also comprise interface (22) to receive power supply system parametre measurement signals (23) and MM programming interface (23). MM (26) saves ratios in the form of multivariable table with input data represented by measurement signals, or in the form of function relating integrated frequency of command signal with pre-determined measurement signals. Power supply system of RF-ignition system comprises control device (2) and supply circuit. The latter comprises switch (4) controlled by signal generated by device (2). The said switch sends intermediate voltage to supply circuit output at frequency governed by command signal. Ignition system comprises power supply system and resonator (5). Resonance frequency of resonator (5) exceeds 1 MHz. The said resonator is connected with power supply circuit output.

EFFECT: guaranteed resonator gain that allows plasma generation.
