Abstract: A switching power supply is provided in two stages with the primary of the power transformer (18) being in the first stage and the secondary in the second stage. The first stage (Stage 1) includes an EMI filter (12) connected to the input of a rectifier (14). The output of the rectifier is connected to a self oscillating, half-bridge, resonant inverter (16) operating in open loop with the primary of the transformer (18) to provide isolation from the power source (10). Feed-forward control is used to compensate for line variations, providing very small output voltage variation compared with input voltage variation. In the second stage (Stage 2), the secondary of the transformer (18) provides an input to post regulator circuitry (20) including a PWM control circuit (34) to regulate the output current using the error signal representing the differences between the current sensed and the desired value.

Abstract: A capacitively coupled fluorescent lamp package having a capacitively coupled fluorescent lamp; an inverter circuit for driving the lamp; and supply nodes for receiving a supply voltage is disclosed. The capacitively coupled fluorescent lamp package includes a resonant circuit lamp driving scheme for driving the capacitively coupled fluorescent lamp. The driving scheme reduces parasitic capacitance leakage current; compensates the reactive power using the secondary side leakage inductance in order to have the resonant frequency approximately equal the inverter circuit operating frequency for current source-type driven circuits; and forms a series resonant sub-circuit with the embedded ballasting capacitor and the secondary side leakage inductance for voltage source-type driven circuits, such that the resonant frequency is substantially less than the inverter circuit operating frequency and that the lamp current is properly shaped along with current ballasting.

Abstract: The liquid crystal display panel of the present invention provides rapid highlighting of the display. To provide highlighting, current to the backlighting lamp 10 is increased from a normal current to a highlighting current. During the transition from the normal current to the highlighting current, the current to backlighting lamp 10 is increased to an intermediate current above the highlighting current, and then decreased to the highlighting current. The increase to an intermediate current provides greater energy to the backlighting lamp 10 than a direct increase from the low current to the highlighting current. The increased energy heats the backlighting lamp 10 quickly to provide the increased light for highlighting. In addition, reducing the current to the backlighting lamp 10 below the normal current when leaving the highlighting mode decreases the time to leave the highlighting mode.
