Abstract
Continuous alternating current is derived from a differential operational amplifier supplied by direct current. The differential operational amplifier produces alternating current located on the positive input of the differential operational amplifier. Output of the differential operational amplifier is received by a transformer to produce alternating current. Voltage from the transformer is fed back to the negative input of the differential operational amplifier to provide feedback for the differential operational amplifier. Whereby direct current provided to a differential operational amplifier is transformed to continuous alternating current.
Claims19
A method to produce alternating current from direct current, which comprises:
- providing a differential operational amplifier, and
- providing a supply of direct current, and
- providing alternating current voltage on the positive input of said differential operational amplifier, and
- providing a transformer to the output of said differential operational amplifier, and
- transporting said output of said differential operational amplifier to said transformer to produce alternating current, and
- establishing negative feedback from said transformer to provide alternating current feedback to negative input of said differential operational amplifier to form continuous alternating current whereby direct current provided to said differential operational amplifier is transformed to continuous alternating current.
