ABSTRACT:
An insect killer has a discharge lamp and its ballast inductor connected in series with a capacitor and the primary winding of a pulse transformer, the secondary winding of which is connected to a high voltage grid. A triac is connected across the series combination of the capacitor and the primary winding and is fired periodically to cause the capacitor to be discharged through the primary winding to impose a high voltage on the grid. By using the ballast inductor to control charging of the capacitor the power dissipation level of the insect killer is minimized.
