Abstract: Abstract of the Disclosure 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° 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.

Abstract: TITLE OF THE INVENTION        A/D CONVERTER HAVING A SELF BIAS CIRCUIT                        ABSTRACT      A self-bias circuit (Rs, Cb) is employed for automatically changing the reference voltage of a comparator (COMP) used in an A/D converter of successive approximation type.  The self-bias circuit is responsive to a voltage at a summing point (a) where an input analog signal, an offset bias and an output analog signal from a D/A converter are added to each other.  The self-bias circuit comprises a resistor (Rs) and a capacitor (CS) so that the capacitor is charged by an average current passing through the resistor connected to the summing point, and the voltage across the capacitor will be used as the reference voltage of the comparator.  When the input analog signal amplitude is small, the reference voltage is shifted so that noises superposed on the voltage at the summing point does not cause the comparator to produce an erroneous output signal with which the state of the MSB is undesirably changed.  As the amplitude increases, the reference voltage rises for ensuring sufficient dynamic range and symmetrical operation for both positive and negative waves.
