Latest Patents

One of Stratton's latest patents is for a high-frequency ballast for gaseous discharge lamps. This invention involves an electronic frequency inverter circuit that receives input electrical power at a lower frequency and energizes a load circuit, including gaseous discharge lamps, at higher frequencies. The design allows for the first and second semiconductors to operate alternatively under current mode control, ensuring that the switches function effectively at high frequencies. The load circuit's impedance varies with frequency, maintaining a constant peak amplitude of the load current despite fluctuations in source voltage. This innovation also includes a high current limit circuit that quickly turns off the switches when excessive current is detected.

Another significant patent by Stratton is a method and apparatus for communication over electric power lines. This invention enables communication from the load to the source by loading the power line voltage wave in a predetermined pattern. This pattern generates corresponding signaling currents at a receiving site. The detection of these signaling currents is achieved by integrating the current in the phase or neutral of the feeder during specific time windows synchronized with the power line voltage wave. This method allows for effective communication even in the presence of steady and transient currents.
