Abstract: An electronic ballast includes a converter, an inverter circuit, a controlling unit, and a current crest factor improvement circuit. The controlling unit issues a first control signal to control the converter and issues a second control signal and a third control signal with opposite enabling/disabling states to control on/off states of corresponding switch elements of the inverter circuit. During a dead time between the enabling state of second control signal and the enabling state of the third control signal, these switch elements are simultaneously in the off state. During the dead time, the current crest factor improvement circuit is triggered to generate a restraining signal. According to the restraining signal, an output power of the converter is decreased to a predetermined value in real time or the converter is suspended.

Abstract: An electronic ballast is provided for controlled preheating of filaments in a discharge lamp. A power converter has a plurality of switching elements and converts DC power from a DC power source into AC power for the lamp. A starting circuit generates a high voltage for starting the lamp. A half-wave discharge detecting circuit detects an absolute value for each polarity peak of a lamp current, calculates an asymmetrical current value from the detected peaks with respect to a predetermined current threshold, and detects a half-wave discharge of the lamp wherein an absolute value of the asymmetrical current value is equal to or more than the current threshold for a predetermined determination time. A control circuit regulates on-times for the switching elements in an filament heating operation wherein the power converting circuit provides a high output frequency for heating each filament of the discharge lamp, and further regulates the on-times to reduce half-wave discharge detected during the filament heating operation.

The ignition pulse generator has, in a series circuit, a pulse capacitor and a switch, parallel to the secondary winding of the ignition pulse transformer and the lamp, wherein the regulator for the voltage value of the transformed ignition pulses sets at the pulse capacitor the voltage applied at an ignition time point. The voltage at the pulse capacitor can be set by means of selection of the switch-on and/or switch-off time points of the switch.

Abstract: A lower-cost ballast circuit for fluorescent lamps is provided. A resonant circuit is formed by a series connection of an inductor and a capacitor to operate the fluorescent lamp. A first circuit and a second circuit are coupled to switch the resonant circuit. Taking the first circuit for instance, a first resistor is connected in series with a first switch for generating a first control signal in response to a switching current of the first switch. The first switch is turned on once the first control signal is lower than a first zero-threshold. After a quarter resonant period of the resonant circuit, the first switch is turned off once the first control signal is lower than a first threshold. Therefore, a soft switching for the first switch is achieved.
