摘要： A discharge lamp driving device capable of detecting a lamp life end reliably in a high or low temperature environment for circuit protection, yet preventing the occurrence of the cataphoresis phenomenon. Impedance elements Z1 and Z1 are inserted respectively between one filament ends of individual discharge lamps La1 and La2 and a node (the ground) having no high frequency amplitude in order to detect a difference between AC components of individual lamp voltages VLa1 and VLa2 in closed loops of the discharge lamps La1 and La2 and the impedance elements Z1 and Z1 in order to judge whether or not the depletion of the emitter occurs. Thus, it is possible to reliably judge the presence of abnormality even when the amplitudes of the lamp voltages VLa1 and VLa2 varies in a range of low to high temperature. Also, since there is no need to provide a DC blocking capacitor to a secondary winding N2 of a leakage transformer LT1, the discharge lamps La1 and La2 can be free from the DC component so as to be prevented from causing the cataphoresis phenomenon.

摘要： An inverter controller dives an inverter to operate at a switching frequency selectively from one of a preheating frequency (f1), a starting frequency (f2), and a lighting frequency (f3) which are different from each other, thereby giving a preheating mode, a starting mode, and a lighting mode. A reset means is provided to make the starting mode upon lowering of a voltage supplied to the inverter below a first threshold, while an inverter stop means is provided to stop the inverter upon detection of abnormality of a discharge lamp. A timer generates a signal determining the start of the preheating, starting, and/or lighting modes, and generates a reset signal disable signal for disabling the reset means, an inverter stop disable signal for disabling the inverter stop means. The inverter controller includes a frequency sweep means for varying the switching frequency gradually from the starting frequency to the lighting frequency. The timer disables the reset means only during a period starting from the selection of the preheating frequency and ending when the switching frequency varies to the lighting frequency, and disable the inverter stop means only during a period starting from the selection of the preheating frequency and ending when the switching frequency begins to vary from the starting frequency to the lighting frequency.

摘要： A inverter AC power supply comprises a chopper connected to receive an AC voltage from a low frequency AC voltage source to provide a smoothed DC voltage, and an inverter providing a high frequency AC voltage from the smoothed DC voltage for driving a load. The chopper includes an inductor and a series connected pair of first and second switching elements which alternately turn on and off for periodically interrupting an input AC voltage to store a resulting energy to the inductor which is subsequently released to charge a smoothing capacitor to give a smoothed DC voltage there across. The inverter shares the first and second switching elements with the chopper and comprises a L-C resonant circuit which is connected across one of the first and second switching elements together with the load to provide an oscillating voltage as the high frequency AC voltage to the load. A self-excitation control circuit is included in the inverter to acknowledge a change in the oscillating voltage. The self-excitation control circuit is connected to control terminals of the first and second switching elements in order to alternately turn on and off the first and second switching elements in response to the change in the oscillating voltage.
