With a total of 4 patents to his name, Gaul's work has had a considerable impact on various applications in the industry.
Latest Patents
One of Gaul's latest patents is a method and apparatus for supplying voltage to a three-phase voltage system. This invention is designed to maintain a defined three-phase voltage system at the output terminals of a transformer device, even when an asymmetrical load is connected. The system utilizes single-phase transformers whose primary windings are supplied with voltage by a pulse-width modulated, three-phase inverter in a bridge connection. The use of voltage regulators allows for precise control of the secondary-side line voltages, ensuring stability in the system.
Another significant patent by Gaul focuses on the power supply for an electrostatic filter. This invention aims to scrub waste gas of foreign matter using an electrostatic filter. The power supply includes a converter that feeds the primary winding of a high-voltage transformer, with the secondary winding connected to the electrostatic filter via a high-voltage rectifier. This design incorporates a control element for the intermediate circuit current, which shields the supply network from the effects of power converter commutations and short-circuits.
