Latest Patents

One of Steneck's notable patents is the "High-frequency oscillator-inverter ballast circuit for discharge lamps." This invention describes a current-fed high frequency oscillator-inverter ballast circuit that employs a parallel resonant tank circuit designed for driving two series-connected discharge lamps via a series ballast capacitor. The system includes a regenerative power supply that activates when there is a fluctuation in the main DC supply voltage, dropping below a predetermined level. This mechanism ensures a constant auxiliary DC supply voltage for the oscillator inverter, which is pivotal for maintaining oscillation and lamp operation. When the main DC voltage rises above the specified level, the regenerative power supply switches off.

An intriguing aspect of this patent is its automatic frequency shift between two frequencies; f.sub.2 during regular operation and f.sub.1 when the regenerative supply takes over, ensuring that lamp current remains relatively constant throughout the operation. The inclusion of a novel high-frequency leakage transformer further enhances efficiency by coupling the high-frequency inverter to the discharge lamp load, providing both current-limiting (ballast) action and controlling the lamp heater current.
