    • An electronic ballast for driving a gas discharge lamp comprises an inverter circuit that operates in a partially self-oscillating manner. The inverter circuit comprises a push-pull converter having a main transformer having a primary winding for producing a high-frequency AC voltage, semiconductor switches electrically coupled to the primary winding of the main transformer for conducting current through the primary winding on an alternate basis, and gate drive circuits for controlling the semiconductor switches on a cycle-by-cycle basis. The drive circuits control (e.g., turn on) the semiconductor switches in response to first control signals derived from the main transformer, and control (e.g., turn off) the semiconductor switches in response to second control signals received from a control circuit. The control circuit controls the semiconductor switches in response to a peak value of an integral of an inverter current flowing through the inverter circuit.

    • An electronic ballast for driving a gas discharge lamp comprises a measurement circuit for measuring a lamp current flowing through the lamp and a lamp voltage produced across the lamp. The ballast comprises a first winding magnetically coupled to a main transformer of an inverter circuit, and a second winding magnetically coupled to a resonant inductor of a resonant tank circuit. The first and second windings are coupled in series electrical connection to generate a voltage representative of the magnitude of the lamp voltage. The ballast further comprises a current transformer having primary windings coupled in series with the electrodes of the lamp. The measurement circuit integrates the current conducted through secondary windings of the current transformer only during every other half-cycle of the lamp voltage to generate a control signal representative of the magnitude of the lamp current that is in-phase with the lamp voltage.

    • A touch dimmer has a three-wire touch sensitive screen that produces an output voltage signal representative of a position of a manual pressure touch along a longitudinal axis of the touch screen. To reduce the occurrence of erroneous position indications due to low-pressure touches of the touch screen, a filter circuit is coupled to the output of the touch screen to prevent the detection of transient touches, and to prevent the detection of low-pressure touches having less than a certain actuation force. As a result, a controller may accurately determine the position of the manual pressure touch. In a preferred embodiment, two filters are coupled to the output of the touch screen. The first filter conditions the output voltage signal to allow the controller to accurately determine whether a manual pressure touch actuation has occurred. The second filter conditions the output voltage signal to allow the controller to accurately determine the position of the manual pressure touch along a longitudinal axis of the touch screen. An alternative embodiment of the touch dimmer uses a four-wire touch sensitive screen that produces a second output voltage signal representative of a position of a manual pressure touch along a transverse axis of the touch screen. The first filter is coupled to receive the second output signal to permit accurate detection of a manual pressure touch actuation.
