Title: Innovations of Sameer Sodhi
Introduction
Sameer Sodhi is a notable inventor based in Vernon Hills, Illinois. He has made significant contributions to the field of electronic ballasts, holding a total of 10 patents. His work focuses on enhancing the safety and efficiency of lighting systems.
Latest Patents
One of his latest patents is for a ballast with a lamp-to-earth-ground fault protection circuit. This innovative ballast includes an inverter and a protection circuit designed to prevent excessive lamp-to-earth-ground fault current. The protection circuit features a transformer that measures the current flowing out of one set of ballast output terminals and the current going into another set. In the event of a substantial imbalance between these currents, the inverter disable circuit terminates inverter switching. Additionally, the protection circuit includes a restart timer that prevents the inverter from restarting immediately after a fault condition.
Another significant patent by Sameer is a dimming control system for electronic ballasts. This system comprises a first circuit and a second circuit. The first circuit is connected in series with the AC line source and receives brighten and dim commands from the user. These commands are communicated to the second circuit by momentarily altering the AC voltage waveforms. The second circuit then provides an adjustable output signal to the inverter circuitry within the electronic dimming ballast, adjusting the output based on the observed AC voltage waveforms.
