Abstract: A dimming electronic ballast control provides flash suppression by igniting the fluorescent lamp at a high power level, and then reducing the power output level to the appropriate dimming set level. The electronic ballast includes an integrated circuit that uses closed loop phase control and a VCO to control a switching frequency of a half bridge, which in turn controls power delivered to the fluorescent lamp. Current through the half bridge is sensed to provide closed loop control. The current sense signal is used to provide a high power level in the electronic ballast during ignition of the lamp, and as a phase detector for the phase control. A rate of change control circuit controls the speed of adjustment between power level settings, especially during ignition of the lamp. The electronic ballast provides a wide linear dimming range with fault detection and flash suppression.

Abstract: A light emitting voltage is applied to the anode (11) and the cathode (13) of a flashing discharge tube (3) (xenon flash lamp) by a charge/discharge capacitor (17). When the voltage of the charge/discharge capacitor (17) does not reach a specified value, for example, a voltage normally required for the light emitting operation of the flashing discharge tube until a specified time, for example, time normally required for charging the capacitor (17), a timer circuit (39) generates a charge stop signal (S3). This signal (S3) allows a control circuit (35) to off−control the switch of a power supply (33) to thereby stop charging the charge/discharge capacitor (17).

Abstract: A power supply and/or ballast optimizes performance of an electrical load, such as a High Intensity Discharge (HID) lamp by monitoring the current and voltage signal driving the load, and calculating a representative portion of the power spectrum being delivered to the load. The calculated portion of the delivered power spectrum is compared to a desired power spectrum, and the input signal to the load is modified in such a manner that the delivered power spectrum will more closely match the desired power spectrum. The input current and voltage, and the frequency at the load are thus not controlled directly, but are an indirect result of applying the modified input power spectrum to the load. By utilizing the input power spectrum in this manner, a power supply and/or ballast provides improved control and performance when used with electrical loads such as HID lamps.

Abstract: A fluorescent lamp driver circuit has regulator (SR); primary circuit of transformer (TF); electronic switches (TR2A and TR2B) and current sensing device (Rsense) connected successively in series across power supply (PSF). Controller (CTRL) is connected to create a feed back loop. The secondary circuit of transformer (TF) is coupled to fluorescent lamps (U10 and U11) via ballast capacitors (C1 and C2). Diode (D1) creates unidirectional current flow, so current sensing device (Rsense) indicates only energy input to lamps (U10 and U11). Capacitors (C1 and C2) are placed physically very close to their respective lamps, enabling good matching of currents through lamps (U10 and U11). Pulse width modulator (PM) with predetermined input is connected to regulator (SR) and, via delay circuit (TD) to controller (CTRL), thus permitting a larger dimming ratio, and further control of input power. Overvoltage detector (OVD) is connected to sense the voltage across inductor (L3) and transformer (TF) giving further control in the event of excess voltage.

Abstract: An integrated circuit (IC12) with both ballast control and driver circuitry and power factor correction (PFC) control circuitry (Fig. 1). At the beginning of preheating, power is provided to the load circuit at a voltage below a voltage at which the lamp can ignite, and the PFC control circuitry can then bring the DC bus voltage up to its running value (Fig. 2). For this purpose, the PFC circuitry is enabled depending on the mode of the ballast control and driver circuitry (Fig. 2). The DC bus voltage is regulated at a lower loop speed when the lamp is running than when the lamp is ramping to ignition, to alleviate DC bus drop. A criterion is applied to determine whether over-current detect signals indicate an actual fault (Fig. 2). For this purpose, detect signals during ignition ramping can be counted and compared with a fault number.
