1. An inverter controller circuit, comprising:

  • a pulse generator circuit for generating a pulse signal for controlling a first switch and a second switch in an alternating fashion so as to allow a primary winding of a transformer to selectively couple to a DC voltage source;

    a capacitor divider electrically coupled to a load and for providing a first feedback signal representing a voltage across said load; and

    a protection circuit coupled to said pulse generator circuit and to said capacitor divider and for shutting down said first switch and said second switch when said first feedback signal exceeds a predetermined threshold after a first predetermined duration.
