Definitions

  • the present invention relates to an electronic ignition circuit for oil or gas burners including a circuit for controlling a charging current provided to a resonator circuit.
  • the ignition circuit further comprising means for resetting, by discharging, the resonator circuit.
  • WO 03/052522 discloses an electronic ignition circuit according to the prior art.
  • the electronic ignition circuit suggested in WO 03/052522 comprises a rectifier, a RC-filter, a MOS-FET type transistor and a resonator circuit including a capacitor and an ignition coil.
  • an object of the present invention to provide an electronic ignition circuit that overcomes the above-mentioned problems of prior art ignition circuits by providing an ignition circuit where the energy accumulated in the resonator circuit is controlled in response to a current flowing in the ignition circuit.
  • the controlling means for controlling the controllable switch may comprise current sensing means for determining the level of the current flowing in the resonator circuit, and a control switch adapted to close the controllable switch in response to a result of the comparison of the determined current level and the predetermined current level.
  • the current sensing means may comprise a shunt resistor operative connected to the controllable switch.
  • the control switch may alternatively be replaced by a microprocessor which closes the controllable switch in response to the determined current level.
  • the controllable switch is an IGBT-type transistor.
  • the electronic ignition circuit may further comprise means for at least partly rectifying an incoming supply signal and filter means operatively connected to the rectifier means so as to filter the at least partly rectified incoming signal.
  • the present invention relates to a method for operating an electronic ignition circuit, the method comprising the steps of
  • Fig. 1 shows a diagram of the electronic ignition circuit according to the present invention
  • the electronic ignition circuit further comprises zener diodes DZ2 and DZ3 to protect TR1 against high voltage spikes on the gate.
  • a current control circuit is formed by components X1 , C6, R4, and R5, where R5 is a current measuring shunt resistor.
  • the electronic ignition circuit further comprises a reset diode, D2, normally inserted as a flyback diode for protection of the transistor.
  • reset diode, D2 is operated as a reset diode.
  • Fig. 4 shows current spikes in the beginning of each positive half period. These current spikes relate to charging of the capacitor in the resonator circuit
  • the combination of the current control circuit and the reset diode is unique in that it becomes possible to make a high efficient, very low cost ignition unit, which will comply with all load demands.
  • the reset diode can be omitted in that the charging of the resonator circuit, in the case of a known load, can be balanced to match the discharging of the resonator circuit via the load.
  • the electronic ignition circuit according to the present invention can be used with all high frequency ferrite core high voltage transformers.
