DC-AC Pure Sine Wave Inverter Circuit

DC-AC Pure Sine Wave Inverter Circuit

The first revision of our PCB board, and the board our circuit was mounted on, is shown in the picture below. This revision had a few traces that were not drawn correctly and so wires had to be added and some traces cut.

The other detail with this revision was that traces were not made for the final filter design and instead space was left for this addition. With these few changes to be made, the team went back and redesigned the PCB board, as seen in Appendix D

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.

In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
