<p>A solid-state power generator or inverter for operating a load such as one or more gas discharge lamps from a DC or rectified AC power source includes two principal circuits, one being a drive circuit with pulse formation derived by negative feedback and the other being an inductively driven or dependent circuit with pulse formation by positive and negative feedback. The circuits operate in 180.degree. phase relationship. The circuits as disclosed are identical except for a capacitor in the first which is not present in the second. The circuits are coupled by a five-winding nonsaturable core transformer in which DC pulses passing through two primary windings induce in one secondary winding a sinusoidal EMF proportional to the product of the two primary currents and, in turn, proportional current flows in the load. Open circuit protection is also provided.</p> |
