Abstract (en)
An ignition system including a spark plug control unit adapted to control at least two stages comprising a first transformer (T1) including a first primary winding (L1) inductively coupled to a first secondary winding (L2); a second transformer (T2) including a second primary winding (L3) inductively coupled to a second secondary winding (L4); said control unit enabled to simultaneously energize and deenergize primary windings (L1, L3) by simultaneously switching on and off two corresponding switches (Q1, Q2) to maintain a continuous ignition fire, wherein means to implement operation is based solely on selective switching of switches Ql and Q2.
