Latest Patents

One of his latest inventions is the "DSP based plasma cutting system." This invention relates to methods and apparatus for controlling a power supply of a plasma arc system. According to the method, any AC input voltage within a range of input voltages is provided into the input stage, generating a rectified output voltage. This rectified output voltage is then directed into the power factor corrected boost stage, resulting in a generated DC signal. The DC signal is subsequently provided into an auxiliary power supply, producing a regulated power signal. This regulated power signal is fed into a digital signal processor module, which generates an output control signal. Finally, this output control signal is sent to the inverter stage, leading to the generation of plasma arc current.

Another significant patent is the "System and method for dual threshold sensing in a plasma ARC torch." This system controls a plasma arc torch circuit using two different current thresholds to manage pilot current. This innovation reduces nozzle wear while ensuring a reliable arc and adequate transfer height. By employing a Hall effect current sensor to monitor low levels of current in the lead that typically carries high current, the system can accurately determine when to ramp pilot arc current to a higher level and when the transferred current can sustain a transferred arc. This capability allows for the timely removal of current from the nozzle, thereby minimizing wear.
