专利汇可以提供Ignition device for oil burner专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide semiconductor ignition device adaptable to an ignition device for oil burner by enabling to prevent switching loss or over-heating of SCR during long continuous operation and to reduce the magnitude of heat generation of SCR until negligible degree.
CONSTITUTION: A LC circuit consisting of a charging and discharging condenser C4 and a primary coil 12 for a boosting transformer 11 is provided and a semicondutor switching element SCR5 is inserted at any position in the LC circuit in order to control the switching of a charging and discharging cycle for the condenser C4. The transformer 11 is provided with a secondary coil 14 connected with a spark generating electrode 17 and a third coil 13 connected in series with a converter diode 16 provided for retrieving energy remained after discharge of C4 into C4 again. SCR5 is charged under the condition that the inductance is kept so as to make the electromotive force mutually induced in the coil 13 bigger than the electromotive force induced in the coil 12 and connected in the polarity so as to cancel the electromotive force induced in the coil 12 by the electromotive force mutually induced in the coil 13.
