ABSTRACT:
A DC-AC converter generates alternating current from direct current voltage for energizing a load with an inductive component. Two transistors connected in series are disposed in a so-called half bridge construction. Two free wheeling diodes are connected in parallel with the transistors and carry the current during the rest time of the transistors. The diodes are connected to the connection point of the two transistors through a control winding of a transformer. The control winding of the transformer controls the transistors. Therefore no additional driver circuit and no outside energy source are necessary for the control and commuting of the transistors of the DC-AC converter circuit.
