Latest Patents
Carroll holds a patent for an electric arc welding power supply, which utilizes SCR rectifiers for output control. This invention features improved output characteristics, fault protection, and both current and voltage controls. The design includes a main power transformer with two secondaries connected in a double wye configuration. The neutral points supply power to one of the output terminals, while independent inductances are in series with each set of secondaries. The system allows for increased phaseback of the SCRs without requiring additional inductance in the output circuit. Furthermore, the fault protection circuit is designed to closely match the time-current overload curve of the SCRs, ensuring optimal performance with minimal size requirements. The control circuit is responsive, providing options for constant voltage output or variable voltage with constant current output, along with line voltage compensation.
