A halogen lamp electronic transformer a power supply circuit, a voltage divider circuit, a control circuit, inductive coils, a push pull oscillator circuit, and a triggering and overload protection circuit. The push pull oscillator circuit consists of a plurality of push pull oscillator transistors, the bases of which are respectively connected to the positive ends of a plurality of inductive coils, with their emitters connected to the negative ends. As such, the positive electrical potential polarity reversal induced at the positive end of the plurality of inductive coils and the negative electrical potential reversal induced at the negative end of the inductive coils switch out and connect the plurality of push pull oscillator transistors to provide for the alternating continuity and cut off of the push pull transistors. This enables the reverse polarity of voltage dividing by the plurality of inductive coils and provides for the current dividing of the current flowing through the push pull oscillator transistors which reduces the heat generated by the push pull oscillator transistors and prolongs their service life.
