A circuit arrangement for producing a high voltage spark comprising a semi-conductor device having a conducting and a non-conducting state, a source of low power unidirectional voltage, such as a battery or accumulator, a feedback coupled transducer means coupled to the source and the semi-conductor device for storing energy from the source during a conduction phase of the semi-conductor device, the feedback transducer device having a primary and a secondary circuit, a diode and a capacitor coupled in the secondary circuit of the transducer device, the stored energy being discharged into the secondary circuit during one of the phases of the semi-conductor device, a sparkgap connected in parallel with the secondary winding of the transducer device, a switching device in the primary circuit of the transducer device for establishing the conducting or non-conducting phases of the semi-conductor device, and a switching means in the secondary circuit for the discharging of the stored energy across the sparkgap, the capacitor being connected in circuit relationship with the primary circuit so that upon switching of the switching device in the secondary circuit, the capacitor discharges over the primary circuit into the transducer and the spark voltage is produced over the sparkgap, the semi-conductor device being isolated from the transducer device electrically or galvanically. |
